We modernize the systems most companies are told to leave alone — COBOL on the mainframe, RPG on the AS/400, aging .NET and Java EE, Oracle Forms with logic buried in PL/SQL. The method is the same in every case: one slice at a time, parity proven before cutover, the business running the whole way.
The source stack tells us what the system does today. It does not dictate where it lands. ModernLift is stack-agnostic by design: the target can be any cloud — public, private, or hybrid — any modern language, any data platform, any orchestrator, any CI/CD pipeline, and any observability stack. Regulated and air-gapped environments are supported. What we hold constant is the behavior: every slice is validated against the legacy before it carries live traffic, whatever the stack on either side.
Each of these is a system someone built carefully and the business came to depend on. None of them is a relic. Pick the stack that matches your estate — the slice loop underneath is the same.
