When upgrading the CA Database Management Solutions from a back-leveled release to a more current release, is it possible to skip intermediate releases?
Yes it is normal practice to skip releases when upgrading these tools. For example, you may be upgrading from release r14.5 and to release r18; it is not necessary to upgrade to the intermediate releases of r15, r16 or r17.
The main consideration as to which releases you can upgrade from and to, is that they must both support the DB2 versions and z/OS release in that environment.
In the above example, both releases are compatible with DB2 v10 and DB2 v11 and with z/OS 2.1.
Compatibility and Lifecycle information for the mainframe products, including the CA Database Management Solutions for DB2 for z/OS can be found on the CA Support portal.
