mBank

killed its mainframe. For real.For real.For real.For real.For real.

The first bank in the world to migrate its entire core banking system built on Accenture’s Alnova to .NET and fully decommission its mainframe.

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.

What could it look like for your stack?

Every mainframe is different. We’ll show you exactly what migration looks like for your codebase.  No generic pitch, no commitment. See it in action.
