v0 · Cutover runbook
Migration from Vercel v0 is the mechanics of moving authority: source of truth for components, env, auth callbacks, and public routes. Design validation already happened in the canvas and preview. Now you need a sequenced cutover—inventory, sync, verify, switch DNS—so operators do not wake up to broken OAuth or vanished search paths.

CodeCross LLC approaches migrate-from-v0 as a cutover runbook, not a redesign brief: map v0-generated Next/React surfaces into your repo, remount auth and data on production services, then flip traffic with redirects already tested. The ship gate is a verified production origin serving the migrated primary journey with account continuity and a rehearsed rollback window before you retire the last public preview URLs.
Why v0 migration is mechanics, not a redesign
Skipping inventory is how teams “migrate” and still paste from the v0 canvas two weeks later. Preview auth is not a migration plan. Sessions issued on preview hosts will not magically work on production.
Fonts, image assets, and metadata that lived only in preview vanish at flip if you do not capture them. Dependency locks drift fast in v0 sessions.
Screenshots alone do not prove the journey. Run the same path on staging and production preview aliases before the final flip.
Separate them before cutover. Export or remount user identifiers to your production IdP. Rotate any keys that ever lived in a shareable preview.
Map every public path v0 exposed. Stage 301s for renamed routes. Submit the production sitemap only after the origin serves content.
The cutover sequence that actually works
Design validation already happened. The work is moving component, env, auth, and route authority without losing accounts or search paths.
01
Include preview-only integrations. Sync source into the owned repo and make it build in CI before anyone calls it migrated.
02
Preview auth is not a plan. Plan forced re-auth or token exchange, and tell operators before you flip.
03
Prefer shared primitives so tokens move once. Diff locks. Freeze a visual checklist of critical screens, then run the journey—not only screenshots.
04
Backlinks from stakeholder shares are real. Retire the last public preview URLs only after the rollback window is rehearsed.
How to
A sequenced cutover. Success is a verified production origin serving the primary journey with account continuity—not a redesign brief.
Step 01
Routes, components, env vars, auth providers, media, and preview-only integrations. Skipping this is how teams still paste from the canvas after “migration.”
Step 02
Map v0-generated Next/React surfaces into the owned repo. Diff dependency locks; v0 sessions drift fast.
Step 03
Rotate keys that lived in shareable previews. Separate demo data from real signups. Sessions on preview hosts will not work on production.
Step 04
Freeze a visual checklist. Prefer shared primitives. Run the same user journey—hydration and data-bound states, not screenshots alone.
Step 05
Stage 301s. Fix canonicals and Open Graph so they never cite `*.vercel.app`. Rehearse the rollback window before retiring the last public preview URLs.

Inventory first: routes, components, env vars, auth providers, media, and any preview-only integrations. Sync source into the owned repo and make it build in CI. Remount secrets and OAuth to production hosts. Prove path parity on a staging alias. Only then change DNS and marketing URLs. Skipping inventory is how teams “migrate” and still paste from the v0 canvas two weeks later.
Freeze a visual checklist of critical screens before cutover. Prefer shared primitives over page-level pastes so tokens move once. Diff dependency locks; v0 sessions drift Fast. Capture fonts, image assets, and metadata that lived only in preview. Run the same user journey on staging and production preview aliases before the final flip—screenshots alone miss hydration and data-bound states.
Preview auth is not a migration plan. Export or remount user identifiers to your production IdP; rotate any keys that ever lived in a shareable preview. If demo data mixed with real signups, separate them before cutover. Sessions issued on preview hosts will not magically work on production—plan forced re-auth or token exchange, and tell operators before you flip.
Map every public path v0 exposed to its production twin. Stage 301s for any renamed routes. Fix canonicals and Open Graph URLs so they never cite `*.vercel.app`. Submit the production sitemap only after the origin serves content. Keep a short overlap where old preview links redirect rather than 404—backlinks from stakeholder shares are real.
Bring the v0 route inventory and who can change DNS. We will say whether this week is a cutover — or an inventory you still do not have.
