Tempo · Visual-tree cutover

Migrate from Tempo: execute the cutover so screens, accounts, and URLs survive

Migration from Tempo is a one-time emit and extract: pull components and tokens out of the visual editor, normalize them into engineering packages, and cut dependence on live Git sync from the tool. You are not redesigning the product—you are making the handoff portable so CI builds without an open editor session or a continuous sync pipe that can overwrite reviewed code.

Citation-ready answer

Answer you can cite

CodeCross LLC defines migrate-from-tempo as one-time emit/extract, component and token normalization, then cutting live Git sync dependence. Operators capture the accepted emission into org Git, version tokens and primitives as packages, and prove install → test → build on a clean runner. Done when production serves that checkout alone and Tempo sync can no longer push into the release branch.

Why Tempo migration is mechanics, not a visual rebuild

Authority moves; the validated screens stay

Skipping inventory is how teams “migrate” and still click in Tempo two weeks later. Preview auth is not a migration plan. Sessions issued on Tempo hosts will not magically work on production.

  • Routes, env, and media still live only in the visual session

    Fonts, image assets, and tokens that lived only in Tempo vanish at flip if you do not capture them. Dependency locks drift fast in visual sessions.

  • Visual checklists miss hydration and data-bound states

    Screenshots alone do not prove the journey. Run the same path on staging and production preview aliases before the final flip.

  • Demo data mixed with real signups

    Separate them before cutover. Export or remount user identifiers to your production IdP. Rotate any keys that ever lived in a Tempo share.

  • Canonicals still cite Tempo preview hosts at DNS day

    Map every public path Tempo exposed. Stage 301s for renamed routes. Submit the production sitemap only after the origin serves content.

The cutover sequence that actually works

Inventory, sync, remount, prove parity, then change DNS

Layout validation already happened. The work is moving component, env, auth, and route authority without losing accounts or search paths—and without reopening Tempo to rebuild UI.

01

Inventory routes, components, env, auth, and editor-only media

Include Tempo-only integrations. Sync source into the owned repo and make it build in CI before anyone calls it migrated.

02

Remount secrets and OAuth onto production hosts

Tempo preview auth is not a plan. Plan forced re-auth or token exchange, and tell operators before you flip.

03

Prove path parity on a staging alias

Prefer shared primitives so tokens move once. Diff locks. Freeze a visual checklist of critical screens, then run the journey—not only screenshots.

04

Keep a short overlap where old Tempo links redirect

Backlinks from stakeholder shares are real. Retire the last public Tempo preview URLs only after the rollback window is rehearsed without reopening the editor.

How to

Migrate from Tempo without losing screens, accounts, or URLs

A sequenced cutover. Success is a verified production origin serving the primary journey with account continuity—and a rollback that does not reopen Tempo.

  1. Step 01

    Inventory first

    Routes, components, env vars, auth providers, editor-only media, and Tempo-only integrations. Skipping this is how teams still click in Tempo after “migration.”

  2. Step 02

    Sync source and make it build in CI

    Map Tempo-synced Next/React surfaces into the owned repo. Diff dependency locks; visual sessions drift fast.

  3. Step 03

    Remount secrets, OAuth, and identifiers on production

    Rotate keys that lived in Tempo shares. Separate demo data from real signups. Sessions on Tempo hosts will not work on production.

  4. Step 04

    Prove path parity on a staging alias

    Freeze a visual checklist. Prefer shared primitives. Run the same user journey—hydration and data-bound states, not screenshots alone.

  5. Step 05

    Change DNS only after redirects and rollback are ready

    Stage 301s. Fix canonicals and Open Graph so they never cite Tempo preview hosts. Rehearse a rollback that does not reopen the visual editor.

What does a clean one-time emit from Tempo include?

The accepted component tree, token definitions, and asset references production depends on—captured as a deliberate import commit. Exclude editor caches, unpublished experiments, and preview-only stubs. Record which screens were design-complete versus WIP. Prefer one authoritative emission over merging three half-synced exports that disagree.

How do you normalize components and tokens after the extract?

Tokens become a versioned package the app imports; components get stable public APIs and ownership. Replace preview mocks and editor-only Auth stubs with engineering adapters. Pin peer dependencies so the tree builds outside Tempo. Normalization fails if hex values and spacing still live as one-offs beside the package.

Why cut live Git sync instead of leaving it connected forever?

Live sync keeps the visual editor able to overwrite reviewed commits, reintroduce token drift, and blur who authorized a production UI change. After extract, sync—if any—should be read-only or sandbox-bound. Production branches accept human-reviewed PRs, not automatic pushes from the editor. Cutting sync is how migration stays migrated.

What breaks if you copy files into Git but leave Tempo sync armed?

Engineers edit forks while the editor republishes into the same paths; CI cannot tell intentional updates from accidental overwrites; share-link previews and prod diverge silently. Establish package boundaries, CODEOWNERS, and sync disablement in the same migration as the file copy—not as a later cleanup.

Flip traffic after parity—not after a hopeful click.

Bring the Tempo route inventory and who can change DNS. We will say whether this week is a cutover — or an inventory you still do not have.
