Migration to new PostgreSQL versions
PostgreSQL is a key component in many business applications and services. Upgrading it safely and efficiently requires specialised expertise, and that is exactly what we offer.
Each new version of PostgreSQL introduces significant advances in areas such as:
Security and encryption
Engine performance
Query optimization
Partitioning and management of large data volumes
Logical replication and high availability
New features for development and analytics
Remaining on an outdated version can expose your organization to:
- Unpatched security vulnerabilities
- End of community support (each version has a 5-year life cycle)
- Missing out on the performance improvements of recent versions
- Growing incompatibilities with current tools and extensions
We follow a proven methodology designed for mission-critical environments:
We review your current version, installed extensions, configurations, application dependencies and any potential points of conflict with the target version.
We create a tailored migration plan covering:
Upgrade method (pg_upgrade, logical replication or dump/restore)
Performance testing
Rollback plan
Maintenance windows
Hardware or cloud requirements
We build a mirror environment to:
Rehearse the full migration
Validate queries, indexes, functions and procedures
Compare performance before and after
Detect incompatibilities before the switchover
We execute the migration using:
Prior replication or synchronisation
Controlled switchover
Data integrity validation
Real-time monitoring
Over the following days we monitor:
System performance
Resource consumption
Errors and operational issues
Fine-tuning of the configuration
Stopping production is rarely an option. That’s why we design migrations aimed at minimal disruption:
During our assessment, we:
- Verify each extension’s compatibility with the target version
- Review behaviour changes between versions that could affect your application
- Check the impact of collation changes (glibc/ICU) on indexes and sorting
- Assess the version life cycle to plan future upgrades
- Analyse the impact on virtualised or cloud environments
Compatibility is the most critical aspect of any PostgreSQL upgrade. A version change can affect extensions, configurations and the platform’s behaviour.
We migrate your database to new versions with all the assurance of the experience behind us.
