Trusted IBM i to .NET Migration – Fixed Scope, Senior Engineers
Migrating from IBM i to .NET Core is a well-understood project: we translate your RPG architectures to C# microservices while keeping the legacy platform under full vendor support until 100% deployment.
The lowest-cost way off IBM i: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support IBM i → .NET Core after migration
- ✓Preserve business IP in modular C# patterns
- ✓Fixed-scope projects run by senior platform engineers
- ✓Stay on vendor support until full deployment
- ✓40-70% savings on legacy support while you plan
- ✓24/7 US-based support for post-migration operations
- ✓Modernize to cloud-optimized .NET Core microservices
Talent drought on legacy RPG
Your team can't hire .NET talent because the legacy RPG platform limits your stack—candidates want modern tooling, not green screens.
Software modernization mandate
Executive leadership has mandated a software modernization initiative—you need a proven path off AS/400 without risking Core business logic.
Expiring contracts, rising costs
Hardware and support contract renewals are escalating rapidly—you need to migrate before costs become unsustainable.
IBM i → .NET Core migration — your questions answered
How do you handle 5250 green-screen interfaces?+
We refactor 5250 green-screen flows into modern web UIs (React, Angular, or Blazor) without altering the underlying business logic. The user experience transforms gradually.
What about RPG system-level pointers and indicator variables?+
Our senior engineers translate RPG system-level pointers and indicator variables into safe, strongly typed C# equivalents. Logic is preserved; risk of runtime errors is eliminated.
Can we maintain integrations that rely on legacy IBM queues (DTAQ/USRSPC)?+
Yes. We wrap legacy IBM queues (DTAQ/USRSPC) with REST APIs and migrate integrations incrementally. Intermediaries remain functional until the final cutover.
What if our vendor support contract lapses before the migration is done?+
Vendor support stays active while your contract is in force. If it lapses before migration completes, our third-party support covers most operational issues (not patches or vendor-level support) so you can continue on your own timeline.

You keep full vendor support on the IBM i until every module moves. If the renewal lapses, our third-party support handles most operational issues on the legacy platform while you finish the transition. Then we manage the new .NET Core application, Azure infrastructure, and API lifecycle—so your team can focus on business growth.
