Understand what you have
The hardest part of modernization is rarely the new platform. It is discovering the rules embedded in the old one — the exceptions, the manual workarounds, the reports someone still depends on.
Replace in slices
Rather than a single cut-over, we place stable interfaces in front of existing systems and move capabilities one at a time.
- Integration layers decouple consumers from legacy systems.
- Each slice is released, measured and stabilized before the next.
- Rollback is planned for every step.
Modernize the data too
New applications on old data structures inherit old problems. Plan data migration and quality work alongside application change, not after it.
