Lovable to Supabase Migration Checklist: 15 Steps to Success

Your Complete Migration Checklist

A successful Lovable to Supabase migration requires careful planning and systematic execution. We have distilled hundreds of migrations into this actionable checklist that covers every phase from preparation to post-launch validation. Print this page and check off each step as you go.

Phase 1: Pre-Migration Audit (Steps 1-5)

Step 1: Inventory all Lovable Cloud tables, noting row counts and column types. Step 2: Document all authentication providers currently in use (email, Google, GitHub, etc.). Step 3: Catalog storage buckets and calculate total file size. Step 4: List all API endpoints your frontend currently calls. Step 5: Identify any Lovable-specific features or plugins that need Supabase equivalents. This audit phase typically takes one day and saves you from surprises later in the process.

Phase 2: Supabase Setup (Steps 6-9)

Step 6: Create your Supabase project and select the region closest to your users. Step 7: Design your PostgreSQL schema based on the audit, optimizing data types and indexes. Step 8: Configure authentication providers to match your current Lovable setup. Step 9: Create storage buckets with appropriate RLS policies for public and private files. Use our database export guide to prepare your data for import.

Phase 3: Data Migration (Steps 10-12)

Step 10: Export all data from Lovable Cloud using the API extraction method. Step 11: Import data into Supabase and verify row counts match the source. Step 12: Migrate storage files and update all URL references in your database. This is the most critical phase and is where our professional migration service provides the most value.

Phase 4: Cutover and Validation (Steps 13-15)

Step 13: Update your frontend code to use the Supabase client library. Step 14: Run end-to-end tests covering auth flows, data operations, and file access. Step 15: Switch DNS and monitor for errors during the first 48 hours. Keep your Lovable environment running in read-only mode as a fallback for one week. Follow our full migration guide for detailed instructions on each step.

After the Migration

Once all 15 steps are complete, schedule a post-migration review after 30 days. Check database performance, auth success rates, and storage costs to confirm that the migration delivered the expected improvements.
