Moving off an old stack or a monolith without betting on a big rewrite. I migrate piece by piece — one service, one component — keeping the business running while the new stack takes over.
Migrate backend components incrementally.
Migrated backend components including PHP-to-Go for data processing and Elasticsearch version upgrades. Each step done with the old and new running in parallel, validated, then cut over.
We pick the lowest-risk component to move first, build the new version alongside, and cut over. From €1,500 for an initial migration.
Initial migration of one component.
Move one component at a time with the old and new running in parallel, validate data and behaviour, then cut over. Each step is reversible.
