What to verify
Check authentication, workspace permissions, CLI commands, extension support, hooks, subagent behavior, and any scripts that call Gemini CLI directly.
If your team has docs or onboarding built around Gemini CLI, update those before the old command path disappears from active use.
Why the migration needs a staged rollout
Google's transition details can change while teams are migrating. Move one workflow first, verify authentication and automation, then update the rest of the team after the new path is stable.
Recommended play
- Treat the migration as a workflow compatibility audit, not a copy update.
- Check official Google dates and changed behaviors before each rollout step.
- Keep the setup and security checks close to the migration checklist so teams can verify permissions, credentials, and automation together.
Gemini CLI to Antigravity CLI migration map
Use this map to find the pieces most likely to break when a team moves command-line agent workflows.
| Area | Check area | What to compare | Risk if skipped |
|---|---|---|---|
| Commands | Local and CI command surface | Local scripts, CI jobs, shell aliases, onboarding docs | Old command paths keep failing after the team switches |
| Authentication | Access and credential model | Personal login, enterprise access, service accounts, environment variables | Users cannot reproduce the workflow outside one machine |
| Extensions and hooks | Automation compatibility | Custom integrations, lifecycle hooks, editor extensions | Automation silently stops or runs at the wrong moment |
| Agent behavior | Runtime behavior | Skills, subagents, context rules, model defaults | The new CLI behaves differently even when commands look similar |
Execution steps
Freeze current Gemini CLI usage
Capture commands, scripts, docs, CI references, auth assumptions, and plugin or extension usage before editing anything.
Map each workflow
For every recurring workflow, write the Antigravity CLI equivalent and mark unresolved behavior differences.
Run a small migration test
Move one repository or one workflow first, verify auth and hooks, then update docs before expanding to the team.
Monitor official updates
Keep a dated change log on the page so users can see what changed after the migration article was first published.
Common pitfalls
Renaming commands without testing workflow behavior
Verify auth, extensions, hooks, and CI outputs before declaring the migration complete.
Ignoring old docs and onboarding paths
Update internal docs, README snippets, and developer onboarding at the same time as scripts.
Letting a time-sensitive page age silently
Add a review date and update the page when Google changes migration details.
Implementation checklist
- Inventory Gemini CLI commands used locally and in CI.
- Map each command to Antigravity CLI behavior.
- Confirm authentication and enterprise access.
- Retest hooks, skills, extensions, and subagents.
- Update internal docs and onboarding.
- Monitor Google docs for deadline or feature changes.
