- pull workspace state from the TFC API instead of per-workspace init
- write migration-summary.{md,json}; replace workspace.tmpl with summary.tmpl
- map TFC vcs settings to SG VCSTriggers (push, PR speculative, file filters)
- add SGDefault*/workspaceOverrides for vcs auth, source kind and triggers
Validate generated payloads against schema/sg-payload.schema.json via yajsv.
- sg-migrate.sh + Dockerfile run the full pipeline inside a container - scripts/migrate.sh: init/apply/enrich/convert/validate/import/triggers/all - merge TFC variable sets, parallel convert/import, register VCS triggers - move convert_hcl_to_json.sh into scripts/
sg-cli exits 0 even when individual workflows fail, so the importer now parses its output. Workflows rejected because their pinned Terraform version is above SG's managed ceiling (1.5.7, last MPL/FOSS release) are re-imported with SGDefaultTerraformVersion, the payload is patched in place, and each case is logged to export/terraform-version-fallbacks.log with a printed notice. Any other per-workflow failure now fails the run. Also: sg_retry captured the wrong exit status (always 0), definitive HTTP 4xx responses are no longer retried, the trigger pass skips workflows that were never created, and failure output no longer echoes the API token.
'sg-migrate.sh completion bash|zsh' prints a completion script for the current shell session; 'init' prints the source line for the user's shell. Runs natively like 'clean'.
Running sg-migrate.sh without a command used to start the whole pipeline; it now prints the help menu, locally, without touching Docker. Usage and hints show the name the user invoked (./sg-migrate.sh) instead of the in-container script path.
Without TFE_TOKEN or a terraform login credentials file, apply used to warn and then fail deep inside terraform with "Invalid provider configuration". Both the host entrypoint and migrate.sh now stop with a clear message before anything runs. Add an explicit provider "tfe" block so tfHostname also applies to the provider, not just the state export.
An expired 'terraform login' session (or a bad TFE_TOKEN) used to fail deep inside terraform. Resolve the token the tfe provider will use, in its own precedence, and check it against /api/v2/account/details first; stop with a clear message on 401/403 or when the host is unreachable.
Every workflow was hardcoded to shared runners unless overridden per workspace. Add SGDefaultRunnerConstraints (default shared) so all workflows can be put behind a private runner group in one place; workspaceOverrides[name].RunnerConstraints still wins per workspace. Validated: type is shared|private, and private requires names.
Move the TFC/SG API helpers out of migrate.sh into scripts/lib/ and add the building blocks the upcoming init wizard, preflight and checklist need: interactive prompt helpers (tty or scripted answers), cached tfvars reads, paginated TFC listing (orgs/projects/workspaces) and SG lookups for integrations, runner groups, workflows and secrets. The enrich script now shares the same token resolution as the provider. Also stop turning curl connection failures into "000000" status codes.
'init' now walks through the configuration instead of copying the example file: it lists the TFC organisations, projects and workspaces the token can see, the SG VCS and cloud connectors and runner groups, and derives the source kind and repo prefix from the chosen connector. Every step falls back to free text when a token is missing or an API call fails, and non-interactive runs keep the template behaviour. The generated terraform.tfvars keeps the example's order and comments; re-running the wizard prefills the current values and keeps a .bak.
Verify up front what used to fail minutes later inside terraform or as API 400s: TFC token and org, that the workspace selection matches anything, SG token and org, every connector / secret / runner group referenced in terraform.tfvars (defaults and workspaceOverrides), SGDefaultSourceConfigDestKind and SGDefaultTerraformVersion format, the exportPath vs export-dir mismatch, and override keys that match no workspace. Runs automatically for apply, import and all; also available as 'preflight'; --skip-preflight bypasses it.
'all' now records each phase's inputs in .sg/state.json and skips phases whose inputs have not changed, so a failed run resumes instead of re-running terraform apply. Import records per payload file which workflows landed and which failed; unchanged, fully imported files are skipped and files with failures are re-imported (sg-cli updates existing workflows in place). --fresh discards the state. --project and --workspace restrict every phase to a subset; apply maps --workspace to the workspacenames variable.
apply now prints a condensed migration summary (workflows per project, sensitive variables skipped, unpinned Terraform versions, non-remote execution modes, renames, failed state exports) instead of leaving it in a file nobody opens. import shows a per-workflow table before the confirmation prompt: create/update, Terraform version with the 1.5.7 fallback marked, runner, triggers, variable and secret counts. 'import --dry-run' stops after the table without touching anything.
Map the API messages users actually hit (unknown connector, missing runner group, repository not reachable, bad approvers, invalid names or VCS kind, rejected token, Terraform ceiling) to a one-line hint naming the terraform.tfvars field to fix. Shown once per distinct hint, both for direct API calls and for sg-cli's per-workflow failures; unknown messages still show the raw response.
After import (or via 'checklist'), write export/post-import-checklist.md
listing everything the migration could not do by itself: secrets to
fill in, workflows that failed to import, Terraform version fallbacks
to verify, VCS triggers that failed, state that could not be exported,
non-remote execution modes and renamed workflows, with deep links into
the SG UI (SG_UI_URL). For every sensitive variable TFC would not
expose, create an SG secret with the value CHANGE_ME, reference it from
the workflow (env var or IaC input, ${secret::<name>}) and patch the
payload to match; --no-secret-stubs opts out. Trigger registration
results are now recorded in the run state.
The integrations list has no ResourceType; the kind (GITHUB_COM, AWS_RBAC, ...) is Settings.kind. Map it from there, make the type filters null-safe, and only treat msg/data as the item list when it is actually an array.
_w_csv_json emitted "[]" twice when the list was empty (grep -v on empty input trips the fallback under pipefail), so the generated file was not valid HCL and preflight reported every field as missing. Validate the file right after writing it, report an unparsable tfvars as such in preflight, remember the SG org / API host chosen in the wizard so a new shell does not need SG_ORG, pretty-print objects in the generated file and separate menu values from their descriptions.
The hint used $SHELL, which is the login shell and was wrong for a bash login shell running zsh, so the bash script got sourced into zsh and broke on the first Tab. sg-migrate.sh now detects the parent shell and 'completion' with no argument prints the matching script; each script also hands off to the other shell's version when sourced by mistake.
The per-workflow plan passed whatever sg_list_workflows returned to jq --argjson and crashed when the response was not a plain array. List helpers now always yield an array (also unwrapping data.Workflows) and the plan guards the value. The wizard no longer asks for the profile name (not required), the repo URL prefix, approvers or the fallback Terraform version — they take sensible defaults and are edited in terraform.tfvars. sg-migrate.sh says when it runs in Docker.
When terraform.tfvars is missing, all runs the wizard and then asks whether to continue right away or edit the file first; only the non-interactive template copy still stops, since it holds placeholders.
Wrap argument parsing and dispatch in main so bash reads the whole script up front. The repo is bind-mounted into the container, and a file edited during a long run was read half-old, half-new, ending in "unexpected EOF while looking for matching quote" after the import had already succeeded.
TFC_* / TFE_* variables (TFC_WORKSPACE_NAME, the TFC_AWS_* dynamic credential settings, ...) only mean something inside Terraform Cloud. A new ignoreVarPatterns input (default ["^TFC_", "^TFE_"]) drops matching terraform and env variables from the payloads, from workspaces and from variable sets, lists them in the migration summary and keeps them out of the sensitive-variable list so no secret stubs are created for them. The init wizard asks whether to strip them. Also fix the secrets link in the checklist (orgs/<org>?tab=secrets).
The "^(AWS|AZURE|GCP)_" filter also matched AZURE_DEVOPS, so an Azure DevOps VCS connector could be chosen as the cloud connector and only schema validation caught it. Both pickers now use the exact kind lists (VCS also accepts AZURE_DEVOPS_SP and GITLAB_OAUTH_SSH and maps them to the source kind), are sorted by name, and preflight rejects a DeploymentPlatformConfig kind outside the schema enum. The validator no longer prints each failure twice.
Presets: SGTerraformVersionSource (carry|preset) plus nullable SGDefaultTerraformVersion and SGDefaultRunnerConstraints. Keys left out of the payload are filled from the org's execution preset by the SG API at import. init offers the preset with the current value shown, preflight reports it, the plan marks 'preset (...)' cells, the checklist explains what changed, and a pin rejected above the 1.5.7 ceiling falls back to the preset when the fallback is null. Flow: numbered phases with timings, live progress lines for terraform and the parallel phases, plain-language preflight with connector/kind/prefix consistency checks, readable wizard review, per-file convert/validate lines, a condensed post-import checklist with group links, and a neutral message when the import is declined. Fixes: init kept the previous repo URL prefix when the connector switched provider (the prefix now comes from the TFC repositories); enrich re-ran on every 'all' because convert changed its recorded hash; quotes in connector names broke the generated tfvars; a RunnerConstraints override with names failed HCL type unification.
sg_api_raw does the request and returns the body on any status, with SG_HTTP_CODE set in the caller's shell; _sg_api keeps the logging and the body-on-2xx-only behaviour on top of it.
…ty iacInputData.data
sg-cli 2.2.1 round-trips every bulk entry through sg-sdk-go v1.1.0's
Workflow struct, whose iacInputData.data map is tagged omitempty, so a
workspace with no Terraform variables reaches the API without the key
and is rejected with "VCSConfig.iacInputData.data: This field is
required."
import_bulk now splits each payload file: workflows with variables go
through sg-cli as before, the ones without are created straight from
the payload via POST .../wfs/ (PATCH when the name exists) followed by
the same state upload sg-cli does. The direct path prints sg-cli's
"Failed to create <name>: <code>: <body>" line on rejection, so the
ceiling fallback, error hints and checklist cover both paths.
Workaround only; TODO(sg-cli) markers show what to remove once sg-cli
ships with sg-sdk-go >= v1.5.7, where the field became a pointer and
"data": {} is sent as given.

…failed import sg-cli's state upload sends a PUT without x-ms-blob-type, which Azure Blob rejects (400 MissingRequiredHeader), and it only recognises a literal "HTTP/1.1 200 OK" as success, so on Azure-backed environments every workflow was created without its state while the run reported "state: exported for every selected workspace". import_bulk now reads sg-cli's per-workflow upload lines and re-uploads every reported failure through sg_upload_tfstate (header included, any 2xx accepted); the direct-create path uploads the same way. Each workflow ends up as state_uploaded or state_failed in the import result, a workflow without its state fails the payload file and is retried on the next import, and the checklist reports the SG-side upload next to the TFC-side export. Workaround for sg-cli; TODO(sg-cli) marks what to remove once its upload sends the header and checks the status properly.
With more than one workflow to import, probe_import imports the first selected workflow of the first payload file on its own and requires both the create and the state upload to succeed before the rest is imported in parallel. An environment problem (a store that rejects uploads, a read-only token, a wrong connector kind) then costs one workflow instead of all of them; the probe workflow is updated again with its file afterwards.
…pdate path sg-cli switches from create to update only when the API's message says "Workflow name not unique", but the API answers 409 "Workflow ID not unique", so every re-import of an existing workflow (a retry, --fresh, the fail-fast probe) failed with that 409 and no state was uploaded. import_bulk now treats a 409 / "not unique" create failure as an existing workflow: it PATCHes the payload entry via sg_update_workflow, uploads its state and drops the failure line, so re-runs are idempotent. The direct-create path does the same fallback in sg_create_workflow. Workaround for sg-cli, marked TODO(sg-cli).
…if needed Customers cloned or forked the repo per release and had no way to pick up fixes. ./sg-migrate.sh update runs on the host: it refuses a non-git checkout, a detached HEAD or dirty tracked files, then fast-forwards the current branch and rebuilds the Docker image only when the Dockerfile changed. Config and output are untracked, so a pull never touches them.
A Git-for-Windows clone with core.autocrlf turns the bash scripts into CRLF and they fail under WSL/Docker.
…rs and workflow group
Connectors and the other SGDefault* values could only be set globally or
per workspace. projectOverrides, keyed by the TFC project name, applies
to every workspace of a project; precedence is workspaceOverrides >
projectOverrides > SGDefault*. Its workflowGroup field picks the
StackGuardian workflow group for the whole project (default
tfc-<project>) and is written into every payload entry's
CLIConfiguration.WorkflowGroup.name, so the importer has one source of
truth; the payload file keeps its sg-payload.<project>.json name.
Overrides now resolve once per workspace into local.effective (each
layer null-filtered before merge()). Object-shaped fields are picked
with the tuple idiom already used for RunnerConstraints, since a partial
VCSTriggers or DeploymentPlatformConfig override does not unify with
the derived value in a conditional.
Both override maps are typed any with a field-name validation:
map(object({... = optional(any)})) rejects entries whose object-shaped
fields differ ("attribute types must all match for conversion to map"),
which already bit workspaceOverrides as soon as two workspaces set
different fields.
The summary gains projects (name -> segment, group, count),
workspaceProjects, workflowGroups and unknownProjectOverrides (keys that
match no TFC project, also flagged in migration-summary.md).
…oudAuthVars) TFC workspaces carry ARM_*, AWS_ACCESS_KEY_ID, GOOGLE_CREDENTIALS and the like; in StackGuardian the cloud connector provides these, and migrated copies fight it. Only TFC_*/TFE_* were stripped so far. stripCloudAuthVars (default true) drops the credential env variables of the family matching each workflow's effective connector kind (AWS_* -> AWS, AZURE_* -> AZURE, GCP_* -> GCP); cloudAuthVarPatterns holds the regexes per family and can be replaced. Env variables only; terraform inputs are untouched. A sensitive credential is stripped as well, so the post-import step does not create a CHANGE_ME placeholder secret that would shadow the connector. Stripped variables are listed in the summary (strippedCloudAuthVars, with the connector kind) and the enrich step applies the same rule to variable-set variables.
…s in the plan The importer takes each project's workflow group from the payload (CLIConfiguration.WorkflowGroup.name, written by the transformer from projectOverrides.<project>.workflowGroup or tfc-<project>); the legacy .sg/workflow-groups.json still applies on top, with a deprecation warning. An existing group is reused (STATUS reuse), a missing one is created unless --no-create-groups (missing!). The old rule that overridden groups must pre-exist is gone. StackGuardian cannot move workflows between groups, so the plan refuses a project whose workflows still live in the group recorded in .sg/state.json (or the default tfc-<project> group) when the target changed (STATUS moved!), and two projects mapped to one group with overlapping workflow names. Problems are listed as ✗ lines, the full plan is still shown (also with --dry-run), and the run stops before the confirmation. The per-workflow ACTION column now says skip for a file that state_import_done will skip, next to update and create. List endpoints are read through a paginated helper (the API pages at 50), and the migration summary shows the group each project maps to plus the new strippedCloudAuthVars / unknownProjectOverrides sections.
The trigger endpoint upserts (a second POST answers 200 "VCS triggers updated"), so re-runs were already safe but re-posted every trigger. do_set_triggers keeps the sha of each posted body in state (triggers.<seg>.sha) and skips a workflow whose triggers are unchanged and already set; --fresh or an edited trigger re-posts. The call goes through sg_set_vcs_triggers, which also treats a 4xx "already exists" answer from older builds as success and reports other errors with the API hint table. Secret stubs were already reused, never overwritten; the log line and the checklist now say so.
With more than one TFC project selected, the wizard's new step 3 asks whether the global connectors and the tfc-<project> groups apply to all projects. If not, it asks per project for the cloud connector, the VCS connector (kind and repo prefix follow, with the usual mismatch warning) and the workflow group — the default tfc-<project>, one of the org's existing groups (GET wfgrps/listall/) or a typed name — and writes the answers as projectOverrides. "same as the default" removes the key so the global value flows through; fields the wizard does not manage (Approvers, RunnerConstraints, ...) are kept. A re-run with existing entries defaults to reviewing them and pre-selects the previous picks. terraform.tfvars is rendered wholesale from the wizard's answers, so a hand-written workspaceOverrides (or projectOverrides) block used to be deleted by the next init. Both maps are now read before the write and re-rendered through a JSON-shaped HCL map renderer (_tfvars_map) that hcl2json round-trips; inner comments are the only thing not preserved. The policy step also asks about stripCloudAuthVars, and the review shows one row per project plus what was kept from the file.
Connector ids, private runner groups and DeploymentPlatformConfig kinds inside projectOverrides are checked like the global and per-workspace ones; a project's VCS connector is compared with the VCS kind that project ends up with; projectOverrides keys that match no TFC project are flagged as a typo (the real project names are listed). The import context states the workflow-group policy (reuse when it exists, create otherwise, or must-exist with --no-create-groups) and warns early when a project's group changed since its last import, which the plan would refuse as a move. One line reports whether cloud credential variables are stripped.
…update semantics README: how init picks connectors and the group per project, the projectOverrides precedence, that hand-written override blocks survive init, the workflow-group rules (reuse/create, never moved, no name collisions across projects sharing a group, mapping file deprecated), the cloud credential variables that are stripped per connector kind, and what a re-run updates (payload change -> update, unchanged -> skip, triggers only when changed, secrets never overwritten). CLAUDE.md follows the code: plan_groups, group_for, the trigger sha, _tfvars_map, wizard_projects, the preflight collectors and the state layout.
… workspace After the real projectOverrides / workspaceOverrides maps, terraform.tfvars now carries one commented entry for every selected project and workspace that has no entry yet, pre-filled with what it gets today: the picked connectors, runners and approvers (a workspace inherits its project's override when one exists), the default tfc-<project> group, and for a workspace the Terraform version it runs in TFC. Fine-tuning becomes "move the entry up and change a value" instead of typing field names; each entry is annotated with its workspace count or project and version. _tfvars_map aligns attribute names and takes per-key notes.
apply already passed the patterns to terraform, but the plan, the import subset, the probe, the triggers and the secret stubs compared exact names, so 'import --workspace team-*' imported nothing. One matcher (bash case / jq ws_selected) now serves all of them; '*' alone means no filter so the unchanged-file skip still applies, and a filter matching nothing is an error instead of an empty success.
…orkspace) The provider only excludes by tag, so the module filters the selected workspaces itself (local.selectedWorkspaces) and everything downstream, state export included, follows. terraform.tfvars keeps the permanent list, --exclude-workspace adds to it for one run, and the run scope helpers move to lib/scope.sh so apply, preflight, the plan, the import subset, the probe and the triggers use one definition. Excluded workspaces are listed in the migration summary; init keeps the list on a re-run and the review shows it.
Until now --project only picked payload files after a full export and had to be the file segment. The module gets tfProjects (names or slugs, [] = all), applied after the name filters: tfe_workspace is read for the name-filtered set because the project of a workspace is only known from there. The orchestrator passes --project as tfProjects, matches payload files by slug so 'My First Project' and my-first-project are the same, and preflight refuses a --project that names no project (a tfProjects typo is a warning) and previews the count the apply will export.
--tag replaces tfWorkspaceTags, --exclude-tag adds to tfWorkspaceIgnoreTags, both are handed to terraform apply and previewed by preflight. Tags are not in the payload, so they shape the export only.
The orchestrator read SG_TFVARS but terraform apply still loaded terraform.tfvars from the module dir, the enrich script fell back to the default path and the Docker wrapper did not forward the variable. The path is now resolved once (absolute), passed to -var-file and to enrich, and the wrapper translates a host path into the container: under /app when the file is in the checkout, mounted read-only otherwise. clean --all only removes the module's own file, and apply warns when both files exist because terraform auto-loads terraform.tfvars on top of -var-file.
… set -u sg_create_workflow tested SG_HTTP_CODE after a $(...) call that never sets it in the calling shell, so with set -u the 409 fallback died before the PATCH and the workflow was reported as failed with an empty message. The '<code>: <body>' text the helper prints already carries the status.
import (and all) write export/run-result.json and run-summary.md: outcome (planned, blocked, success, failed), the scope flags, the group table, the plan problems and one row per workflow with plan, result, Terraform version, state and trigger status; the markdown is made for a CI job summary. Import results and state gain an 'updated' list so a PATCHed workflow is told from a created one (the probe workflow counts as created). --dry-run is documented for 'all' too: the local export runs, nothing is created in StackGuardian.
…uns keep unmanaged keys A file written by an older version keeps working (missing settings take their defaults), but users had no way to see what is new short of diffing the example. init --upgrade appends every setting the file lacks with the comment and default from terraform.tfvars.example under a dated header and touches nothing else, so hand comments survive and it runs without a terminal; preflight names the missing settings until then. The wizard re-run now also carries over settings it does not ask about (tfProjects, cloudAuthVarPatterns, hand-added keys) instead of dropping them.
…e's uncommented ones The first version derived the list from terraform.tfvars.example, so the override maps, cloudAuthVarPatterns and tfHostname were never appended. The list now comes from variables.tf; a setting the example only shows commented out is appended that way (plus 'key = <default>' when the default fits on one line), a mention in the file counts as present so a second run adds nothing, the result is parsed and rolled back if broken, and init writes tfHostname so a fresh file is complete.

Summary
Turns the migrator from a hand-driven
terraform applyplus manual editing into one guided pipeline:./sg-migrate.sh allconfigures, preflights, extracts and transforms the workspaces, merges Variable Sets, converts and validates the payloads, and bulk-imports them into per-project workflow groups. The transformer gains per-project output, a migration summary, API-based state export, VCS trigger mapping and execution-preset support.Suggested review order:
