Modernization thatsequences correctly.
Legacy systems rarely fail because nobody knew they were old. They fail because the replacement was sequenced badly — the dependency nobody mapped, the integration that had to hold, the cutover with no way back.
Architecture before migration
Enterprise and integration architecture that describes the system you actually run — including the parts that are undocumented, the interfaces that are load-bearing, and the constraints that will not move.
Modernization in tranches
Application and platform modernization staged so each tranche delivers on its own and leaves a working system behind it. No eighteen-month cutover with a single point of failure at the end.
Interfaces that outlive the project
API and integration design treated as a long-lived contract rather than project scaffolding, so the next modernization does not start by unpicking this one.
