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

  1. Treat the migration as a workflow compatibility audit, not a copy update.
  2. Check official Google dates and changed behaviors before each rollout step.
  3. Keep the setup and security checks close to the migration checklist so teams can verify permissions, credentials, and automation together.

Execution steps

01

Freeze current Gemini CLI usage

Capture commands, scripts, docs, CI references, auth assumptions, and plugin or extension usage before editing anything.

02

Map each workflow

For every recurring workflow, write the Antigravity CLI equivalent and mark unresolved behavior differences.

03

Run a small migration test

Move one repository or one workflow first, verify auth and hooks, then update docs before expanding to the team.

04

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.
