see  APAR #: RI92597 . Title: CA DATACOM CORE PRODUCTS FOR Z/OS 14.0 EOS

Environment:

Instructions:

The procedure to upgrade from CA Datacom 14.0 to 15.x is as follow: 

- 1- Follow the README informational APARs: 

#: RI67375 for 15.0.

#: RI86635 for 15.1

Note: We recommend to upgrade to 15.1 and apply any required/recommended APARs to 14.0 and 15.x. Also recommend to upgrade maintenance. 

 

-2- Execute DDSDCLM report in your 14.0 environment to cleanup Data Dictionary. 

DDSDCLM report should be clean. 

This step may take some time and need to be executed prior the upgrade itself with the help of CA support. 

 

-3- Download the CA Datacom/DB 15.x product via Pax or CSM method. To install all the SMP/E libraries. 

 

-4- Choose the upgrade procedure from the three documented methods at: 

https://docops.ca.com/ca-datacom/15-1/en/installing/upgrading-multi-user-facility-muf-version-14-0-to-15-x 

 

We would recommend the Active Upgrade Procedure or Traditional Procedure.

 

The Active Upgrade Procedure is the most common procedure used by clients.

It can be done with minimal disruption to the existing environment. 

It is documented here:

 https://docops.ca.com/ca-datacom/15-1/en/installing/how-to-perform-an-active-multi-user-facility-upgrade

With Active Upgrade, many steps can be done prior the upgrade itself to finally consist of: 

-a- Switching Multi-User CUSLIB and CABDLOAD (from 14.0 to 15.1). Allowing to switch back libraries to 14.0 if something wrong. 

-b- Updating DD, DQ and DBID 1000. These actions can be done at a later time after item a.
