What this is
Legacy systems rarely get replaced all at once, and they shouldn't — a rewrite that takes eighteen months and freezes feature work is its own kind of risk. We audit what's actually there, find the parts safe to leave alone, and migrate the rest in pieces small enough to roll back if something goes wrong.
Every migration ends with documentation your own engineers can read, not just ours.
What's included
- Legacy system & dependency audits
- Incremental, zero-downtime migration
- Documentation & knowledge transfer to your team
- Compliance-aware architecture where regulation applies
