mBank
killed its mainframe. For real.For real.For real.For real.For real.
100%
MAINFRAME OFF
.NET
Full migration
#1
WORLD FIRST
Same code. New world.
The business logic running on the mainframe is identical to what now runs on .NET, adapted and optimized for the new environment, never rewritten from scratch.
IBM Db2 -> MS SQL Server
Raincode’s compile-time database remediation allowed code written for Db2 to run on SQL Server without touching application code or embedded SQL statements.
Full decommission.
Not a pilot. Not a cherry-picked workload. mBank turned off its mainframe altogether. No footprint left. This is what done looks like.
Getting off the mainframe was not just a nice-to-have improvement; it was a key factor in mBank’s long-term existential ambition.
