Checklist FAQs

What is the correct order to migrate from Lovable Cloud to Supabase?

Always start with the audit phase to map your data structure. Then migrate the database first, followed by auth users, then storage assets. Only do the frontend SDK swap last — after everything is verified in Supabase.

What steps are most commonly skipped — and what breaks?

The three most-skipped steps are: (1) row-count validation after database import — causes silent data loss, (2) storage URL re-mapping — causes all images and files to break, (3) RLS policies — leaves your data publicly exposed.

How long does it take to complete the full checklist?

DIY: 2–4 weeks of part-time engineering. With our migration tool and service: 3–7 business days with expert oversight.

Do I need to shut down my Lovable app during migration?

No. The correct approach is to run Lovable Cloud and Supabase in parallel, validate everything on Supabase, then do a traffic switch. Keep Lovable Cloud running for 30 days as a fallback.
