Why Not Just...?
"Why not use SQL Server Express (free)?"
SQL Server locks you into Windows licensing and ODBC nightmares. PostgreSQL is free forever, runs anywhere, and AccessToPostgres handles the schema migration automatically—no manual ODBC linking.
"Why not just export to CSV?"
CSV loses your relationships, queries, and forms. AccessToPostgres preserves your entire schema while eliminating the file-size prison.
Eliminate Access Limitations
Eliminates 2GB Limit
PostgreSQL backend handles 100GB+. Access 2GB limit solution.
Stops Multi-User Corruption
Cloud backend prevents "database in use" errors. Access corruption fix.
Keep Your Forms
Access frontend links to Postgres backend via ODBC scripts. Access backend migration.
One-Click Migration
Schema + data + relationships auto-converted. Access to postgresql.
No VPN Required
Secure cloud connection strings auto-generated. Works from anywhere.
Multiple Cloud Targets
Export to Supabase, AWS RDS, or self-hosted PostgreSQL. Your choice.

Migration FAQ
Q: Can I keep using my Access forms?
A: Yes. AccessToPostgres creates ODBC linked tables in your Access frontend that point to PostgreSQL backend. Your forms, reports, and macros continue working—you just eliminated the corruption and size limits.
Q: What about my VBA code?
A: The DIY tool migrates data only. VBA remains in Access (frontend). For complex VBA conversion (backend logic), our DFY service converts it to Python/JavaScript and deploys it to cloud functions.
Q: Do I need PostgreSQL knowledge?
A: For DIY: basic database concepts help but the tool guides you through connection setup. For DFY: we handle everything including Supabase/AWS setup and provide documentation for your team.
Q: Is there a rollback option?
A: Yes. The migration creates a full backup and rollback scripts. DFY includes rollback insurance: if anything goes wrong during cutover, we restore your original system within 24 hours.
Q: What if we need to migrate to SQL Server or MySQL instead of PostgreSQL?
A: The DIY tool is PostgreSQL-only. For migrations to SQL Server, MySQL, or Oracle, book the DFY service — we handle any backend.
