Upgrading information for CICS when changing releases of CICS, z/OS, Db2 or IMS

Troubleshooting


Problem

You would like to know what problems you might encounter when you upgrade from one release of CICS to another. You also want to know what CICS problems you might encounter if you change to a new release of z/OS, Db2, IMS, or to a new Z mainframe.

Resolving The Problem

Select the appropriate link for the product you are installing to be taken to the corresponding table. Then, click the search link to the right of the release of the product you are installing.

 

If you are upgrading from an old release, you should click the search links for ALL the intervening releases. For example, if upgrading from CICS TS 5.3 to 5.5 then you should click the search links to the right of "CICS Transaction Server for z/OS 5.4" and "CICS Transaction Server for z/OS 5.5".
