Firebird database migration
Most Firebird upgrades are done by your own developers with the Practical Migration Guide - that works for about 90% of databases. Use our professional migration service when metadata is messy, the deadline is tight, the version is older than 2.5, or you must move many servers with automation.
How to migrate
DIY - ~90%
Application and database developers follow the Practical Migration Guide and the YouTube tutorials. No major issues for most databases.

We adjust metadata and SQL, can patch Firebird sources (for example custom builds that exclude keywords), and typically finish in 3-4 weeks.

A custom kit plus high automation - the Migration Framework, adapted to your application and rolled out across customers and sites.
Migration FrameworkVersion path
Every migration targets Firebird 5.0. From 2.5, 3.0, or 4.0 that is the usual path (guide or service). From 1.0-2.1 it is much harder - a common reason to use the service.
When to use the professional service
Complex structure
Lots of manual metadata and SQL changes. We handle those, including custom Firebird builds when reserved words block the upgrade.
Fixed deadline
When the cutover date is not negotiable, we run the migration as a project. Typical calendar span is 3-4 weeks.
Legacy versions
Firebird 1.0-2.1 need more than a backup/restore. Our team has done these jumps many times.
Many databases
Multiple servers and customers need a repeatable kit, not one-off scripts. That is what the Migration Framework is for.
How long it takes and what it costs
Estimate depends on metadata size and complexity (tables, procedures, triggers) and how many SQL statements must be checked and fixed. Figures below are IBSurgeon workdays - calendar time is longer because you review intermediate results.
Send a metadata-only backup with your request for an exact estimate.
