In IBM Sterling Order Management staged upgrade from 9.2.1 to 9.5, can only RCP SOM be upgraded to 9.3 with RCP COM still on 9.2.1?

Question & Answer


Question

There is a staged upgrade implementation of IBM Sterling Order Management(OMS) from 9.2.1 to 9.5. IBM Sterling RCP SOM 9.2.1 and COM 9.2.1 are pointing to OMS 9.2.1. The plan is to install only RCP SOM 9.3 on OMS 9.5. Post SOM installation RCP COM 9.2.1 will still be pointed to OMS 9.2.1.
What's the product recommendation?

Cause

RCP SOM 9.3 and COM 9.2.1 combination is not a tested and supported approach.

Answer

In RCP, there is no option to upgrade only SOM and not the COM. As part of RCP db migration task both COM and SOM will be upgraded to the latest version of RCP i.e. 9.3. If someone tries to connect old COM client i.e. COM9.2.1 using old app server, with the latest DB i.e. COM9.3; then it is not a tested and supported approach.
The recommendation from product side is to upgrade both RCP COM and SOM to V9.3.
