# Migration overview

Migrate to Stratix from another evaluation tool.

Coming from another tool? These guides cover the major patterns.

## General migration approach

1. Inventory what you have in the source tool
2. Pilot a single team / feature for \~2 weeks
3. Run dual (Stratix + old tool) for one full release cycle
4. Decommission old tool when scores correlate
