Proven IBM CICS Transaction Gateway to z/OS Connect Migrations by Senior Engineers
Yes, migrating IBM CICS Transaction Gateway to IBM z/OS Connect Enterprise Edition is a well-understood project. Our senior z/OS engineers assess your topology, refactor CICS assets, and deploy REST APIs directly
The lowest-cost way off IBM CICS Transaction Gateway: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support IBM CICS Transaction Gateway → IBM z/OS Connect Enterprise Edition after migration
- ✓Fixed-scope migration projects, no surprise costs
- ✓Senior engineers with decades of z/OS experience
- ✓Keep CICS Transaction Gateway under vendor support during planning
- ✓Publish native RESTful APIs from your mainframe
- ✓Consolidate communication paths to simplify architecture
- ✓40-70% savings vs vendor support renewals on legacy platform
Incompatible legacy CTG client libraries
Your CICS Transaction Gateway client libraries may not easily call REST endpoints. We bridge that gap by refactoring assets directly for z/OS Connect, without forcing a full application rewrite.
Fear of interrupting active mainframe operations
Our consultants work alongside your team in phases, not big-bang cutovers. The legacy platform stays under vendor support as long as your contract is active, so you control the timeline.
Pressure from cloud teams for REST APIs
Internal cloud development groups need RESTful endpoints. z/OS Connect EE delivers them natively on IBM Z, letting you modernize in place without cloud migration risk.
IBM CICS Transaction Gateway → IBM z/OS Connect Enterprise Edition migration — your questions answered
How do you migrate from CICS Transaction Gateway to z/OS Connect?+
We assess your current CTG topology, identify existing CICS assets and communication paths, then deploy z/OS Connect EE to publish RESTful APIs. The project is phased and non-disruptive.
What happens if my vendor renewal lapses during the move?+
If your IBM CICS Transaction Gateway support contract expires, our third-party support covers most operational issues on the legacy platform—though it is not vendor support and does not include vendor patches. You can still complete your migration on your timeline.
Can my internal cloud development teams use the new REST endpoints?+
Yes. z/OS Connect Enterprise Edition exposes your mainframe CICS as native RESTful APIs that standard cloud tools can consume directly.
What if my current CTG client libraries are outdated?+
We handle that. Our engineers refactor legacy interfaces for z/OS Connect, bypassing the need to update old CTG libraries.
