Hi,
We are migrating from CICS TS 3.1 to CICS TS 4.1. We are looking for a Migration guide so as to complete the migration properly with as less issues as possible. Can any one provide any such document or link to get one?

Thanks in advance for the help.

Regards,
Anoop

On the left side, click on the CICS Transaction Server for z/OS, Version 4.1 box
Then click on the Upgrading box.
Then click on the Upgrading from Version 3 Release 1 box.

Thanks Robert for the reply. I am looking more from application code changes to make it work properly (compatible) with new version of CICS TS. Please let me know in case I have missed some thing in the link provided.

From an application standpoint, I can't think of the last time a CICS release was not compatible with earlier releases -- except when IBM dropped support for macro code, and this was announced for years before it happened. There generally is new functionality that requires application code changes to take advantage of, but the application will almost always continue to run under the new release without change.

If you look in the CICS 4.1 Language Reference and Programming Guide manuals, they will list any application issues near the front of the manual.

Thanks a lot Robert for guiding me. I will look in to it and will come back in case of questions.
