Database Migration & Zero-Downtime Upgrade
Moving or upgrading a production database is where data gets lost and businesses go dark - so I do it safely. I handle PostgreSQL and MySQL version upgrades and cross-host or cross-cloud migrations using logical replication for near-zero downtime: the new database is built and kept in sync with the live one while it keeps serving traffic, so the cutover is a quick switch rather than a long outage. Every move includes pre- and post-migration validation - row counts, checksums and key constraints checked on both sides - plus a tested rollback plan so you are never stuck if something looks wrong.
This suits UAE businesses moving off an old server, consolidating to a managed service like Amazon RDS or Aurora, or relocating to the me-central-1 (UAE) region for data residency. I run a dry-run cutover first, schedule the real switch for a low-traffic window for your Dubai, Abu Dhabi or Sharjah users, and do a performance check after the move so the new database is at least as fast as the old one.
This differs from my Database Management service, which is ongoing tuning, backups and day-to-day administration. This gig is a one-time migration or upgrade project with a clear start, cutover and finish.
What's included
- Migration plan - Documented plan covering scope, sequence, risks and the cutover window
- Logical replication cutover - New DB kept in sync live for a near-zero-downtime switch
- Pre/post validation - Row counts, checksums and constraints verified on both sides
- Rollback plan - A tested fallback so the move is reversible if needed
- Performance check - Post-move tuning so the new database is at least as fast
- 7-day delivery - Plan, dry-run and cutover completed within a week
How it works
- 1Assess + plan
I review the source database, agree the target, and write the migration and rollback plan.
- 2Replicate + dry-run
The target is built and synced via logical replication, then I run a full dry-run cutover and validate the data.
- 3Cutover + verify
The real switch happens in a low-traffic window; I verify counts, run the performance check and hand over.
