# Migrate to TeamCity ## Quick Start ```bash teamcity migrate # detect + convert + write .tc.yml files teamcity migrate --dry-run --json # preview as structured JSON teamcity pipeline validate f.tc.yml # schema check teamcity project vcs create --url <repo-url> --auth anonymous -p ProjectId # create VCS root first teamcity pipeline create name -p ProjectId -f f.tc.yml --vcs-root <VcsRootId> teamcity run start PipelineId --watch ``` Run `teamcity migrate` from the repo root -- detection scans `.github/workflows/` and `bamboo-specs/` relative to the current directory. ## Reading the report - **Needs review** -- problems inside the generated YAML: TODO stubs, dropped steps, reusable-workflow placeholders. Fix these in the file before creating the pipeline. - **Manual setup needed** -- work the converter cannot do. Sort each item onto one of two sides: YAML edits (secrets, matrix expansion, expression `runs-on`, `container:`/`services:`) go before `pipeline create`; server-side configuration (connections, `if:`-derived branch filters, triggers, notifications) comes after. The checklist below orders them. - Exit code 1 means at least one source failed to convert *or* one generated file failed schema validation -- files that converted cleanly are still written. Read the per-file ✓/⚠/✗ lines instead of treating exit 1 as total failure. - `--json` prints `{"sources": [...], "results": [...]}` to stdout; each result carries `outputFile`, `yaml`, `needsReview...
