Mainframes paid for themselves. Modernize the parts that need to move, leave the parts that don't, and stop pretending it's all-or-nothing.
What runs, what matters, and what genuinely needs to move — with the dependency map to prove it.

APIs, events, and contract testing that let modern services talk to the mainframe safely while you migrate.
Migrated the customer-facing experience off the mainframe without taking the policy engine down.
Often. The mainframe is a perfectly good database in some shapes — the question is the experience around it.
