No-code & vibecode migration guide

Seven phases: Decide → Audit → Design & content → Rebuild → Cutover → Stabilize → Offboard. Do not start the rebuild until audit and design intent are locked.

• Lock design intent first (even on the old stack), then change platform
• Phased cutover beats a big-bang weekend every time

Inventory flows, data, users/auth, integrations, content, SEO baseline, and analytics. Tag every item carry, rebuild, or retire.

• Happy paths, edge cases, admin, and roles
• Entities, relationships, orphans - what must survive cutover
• Plugins and glue that should become owned APIs
• Top URLs by traffic before you rewrite anything

Keep (and elevate) core product logic, user accounts, core records, and brand patterns. Rebuild plugins, auth/data model, tests, performance architecture, and a real design system.

• Pixel-perfect clone is usually the wrong goal
• Owned integrations beat platform workarounds long-term

Migrate tokens and components, not one-off page styles. Map IA, CMS fields editors will touch weekly, locales, and a publishing workflow that is not archaeology.

• Color, type, spacing, radius - on real components
• Decide locales before build, not after launch
• Blog and service pages need a content model, not a dump

Years of links should not die. Build the old→new URL map, 301s, titles/meta, canonicals, sitemap, and an internal-link pass after redirects go live.

• Locale and trailing-slash rules written down
• Search Console and Analytics cutover notes
• Smoke-test the top 20 URLs on cutover day

Repo ownership, auth, data dry runs, parallel run where needed, real API integrations, critical-path tests, and a performance budget. For vibecode: eval, guardrails, and cost control.

• Dry-run data migration before the flip
• Replace fragile demo glue with production paths
• Second-engineer handoff should not require archaeology

Freeze window, final sync, DNS/hosting flip, redirects live, forms/auth/payments/webhooks, analytics firing, rollback criteria, and named owners.

• One war-room owner for go / no-go
• Rollback trigger written before you start

Watch errors and redirect misses, patch content gaps, and define done as parity + ownership + ship speed - not a prettier homepage alone.

• Redirect miss log → patch weekly
• Optional maintenance and support window after cutover
