Migration in flight — sound familiar?
- ▸ Replication slot bloat — WAL retention eating disk because the logical replication slot can't advance; cutover window keeps growing while the source runs out of headroom.
- ▸ Logical replication breaks on DDL — Every schema change mid-stream tears down the subscription — and the application team can't freeze schemas for a 2-week cutover.
- ▸ pg_largeobject doesn't transfer — pg_dump skips large objects without --blobs; sequences lose their ownership relationship; you only catch it after cutover when sequences drift.

Seamless PostgreSQLDatabase Migration Services
In short: A PostgreSQL migration covers version upgrades (9.x→18.x), Oracle, SQL Server, and MySQL cross-platform conversions, and cloud moves to AWS RDS/Aurora, Azure, or Cloud SQL. A six-phase methodology — assessment, planning, preparation, execution, validation, and go-live — uses Ora2Pg, AWS DMS, and logical replication for sub-30-second-cutover zero-downtime migrations.
Migrate PostgreSQL with zero downtime and guaranteed data integrity. Expert upgrades, cloud transitions, and comprehensive risk mitigation through proven methodologies.
