# Database migration and replication

> Switching database systems, version upgrades and replication: planned, tested, with a fallback option and no data loss. Legacy systems too.

A move to a different database system, a version upgrade or replication to a second server: we plan the cutover, test it beforehand and switch over without data loss.

Migration & replication Service

- **Switch:** between database systems
- **Upgrade:** to new versions
- **Replication:** to further servers
- **Safeguards:** tested, with fallback option
- **Goal:** no data loss

## How we run a migration

Not a move in one go, but a planned cutover with a way back.

- Analyse in depth: We look at the data structure, dependencies and the applications that access the database.
- Plan the cutover: We set the order, timing and fallback option so that downtime stays as short as possible.
- Test beforehand: The switchover is rehearsed before it happens in live operation.
- Switch over: We carry out the migration without losing any data.

## Even when standard tools are no longer enough

We step in precisely where common migration tools reach their limits.

- **Legacy system without export:** The current system has no clean export interface but needs to be replaced.
- **Unusual data structures:** The standard tools cannot map your data structure.
- **Minimal downtime:** Your business cannot stand still for long. We plan the cutover so the switchover stays short.
- **Step by step:** If software depends on the database, we can modernise it step by step as well, without a big bang.
