Migrating a production project to another region (ap-southeast-2 → us-east-1) with Auth + Storage — lowest-downtime approach?

[GenAI-Expert101]

I need to move a live production project from ap-southeast-2 (Sydney) to us-east-1 (N. Virginia) to co-locate it with my backend (AWS EC2 in us-east-1). Right now every DB call crosses the Pacific, so API requests are ~700ms (should be ~150-200ms co-located) and direct Postgres pooler connects take ~2s.

My understanding is that a project's region can't be changed in place — you create a new project in the target region and migrate into it. I'd like to confirm that and learn the cleanest path.

My stack:

• Postgres (public schema = all app data; extensions incl. uuid-ossp)
• Supabase Auth / GoTrue (auth.users + identities; a table has an FK to auth.users)
• Supabase Storage (buckets with uploaded files)

It's a live project with real customers, so I want minimal downtime and zero data loss.
Questions for anyone who's done this:

1. Is creating a new project + migrating the only option, or is an in-place region change possible now?
2. Best low-downtime cutover approach? (I'm planning: pg_dump/pg_restore for public + auth + storage schemas, then a final delta sync during a short maintenance window.)
3. How did you migrate Auth users/identities cleanly so logins + the auth.users FK keep working?
4. How did you copy Storage objects (the actual files, not just the storage.objects rows) to the new project?
5. Any gotchas — Auth JWT secret, RLS policies, OAuth redirect URLs, pg client version matching?

Any battle-tested runbook or scripts appreciated. Thanks!

I have not done the migration so will only confirm that is the only way. You are not missing some secret way.

The migration guide https://supabase.com/docs/guides/platform/migrating-within-supabase/backup-restore covers how to copy the storage data with a js script. Auth should just transfer as password will work. Users will have to login though.

2 is a good idea basically prove you know what to do, don't have steps missing or some config you need to make sure you set up.
