Migrating from Vercel: deployment checklist

A practical sequence for planning, testing, and de-risking a move away from Vercel.

STEP 1

Classify workloads

Separate static pages, edge functions, serverless APIs, containers, cron jobs, and background workers.

STEP 2

Map env vars, build commands, runtime versions, redirects, caching, domains, and preview environments.

STEP 3

Validate auth, webhooks, cold starts, logs, rollbacks, observability, and CDN behavior.

STEP 4

Use staging then weighted DNS or proxy routing. Keep a proven rollback target available.

Keep the old path available until the new workflow has passed functional, operational, and rollback tests.
