PostgreSQL Infrastructure Discovery
Database sizes, used extensions, user roles, pg_hba.conf access rules, and dependencies are extracted.
MIGRATION SERVICES
PostgreSQL Migration and Database Relocation Services
PostgreSQL migration is a service that involves the seamless transfer of database schema, data, user roles and permissions, extensions, and application connections to a new environment without data loss.
What is PostgreSQL Migration and Database Relocation Services?
Using only pg_dump and pg_restore tools during the PostgreSQL migration process can lead to long-term service interruptions and performance bottlenecks, especially in large databases.
The process includes a detailed analysis of the current PostgreSQL version, used custom extensions (PostGIS, pg_stat_statements, etc.), collation/locale settings, WAL (Write-Ahead Logging) size, and disk infrastructure. Depending on the tolerance for downtime, either physical backup/restore (pg_basebackup) or logical replication methods are preferred to achieve a near-zero-downtime live transition.
Service scope
Target Environment Preparation
Target version, locale/encoding compatibility, memory/storage parameters, and network security rules are configured.
Secure Data Transfer
Local tools (pg_dump/pg_restore), physical backup, or logical replication are used to transfer data.
Validation and Verification
Schema objects, row counts, sequence values, query performance, and application connections are verified.
WHO IS IT FOR?
Who is it for?
- Organizations moving from on-premise servers to managed services like AWS RDS PostgreSQL, GCP Cloud SQL, or Azure Flexible Server.
- Teams looking to upgrade to newer versions of PostgreSQL without risking data loss from older versions.
- Organizations aiming to relocate their PostgreSQL infrastructure to a new data center or server.

Frequently asked questions
What changes occur during the transition to managed PostgreSQL (AWS RDS, etc.) services?
Superuser privileges are restricted, and the list of supported extensions varies by provider; backup and maintenance processes are transferred to the cloud panel.
How can downtime be reduced in large PostgreSQL databases?
By using logical replication or WAL-based tools to pre-synchronize data, the downtime period is reduced to just a few seconds of redirection time.
Do you perform migrations from PostgreSQL to MSSQL or from MSSQL to PostgreSQL?
Migrations between different database engines (heterogeneous migration) require changes in schema, data types, SQL procedures, and application code; these are handled separately from standard migrations.
