  • An upgrade to z/OS 2.3 involves applying maintenance to multiple components of Common Services for z/OS r14.1. 
    • Earlier z/OS releases only involved one component, SERVCS FMID CEI0E10
    •  z/OS 2.3 requires maintenance to SERVCS and CAIRIM FMID CAS9E10
  • Maintenance can possibly require up to 19 fixes across different components if currently running z/OS release 2.1 or below
  • Intent of this article is to provide instructions to accomplish the upgrade most easily
What is the easiest path to follow to upgrade Common Services r14.1 for compatibility with z/OS 2.3 if currently executing in a z/OS 2.1 or earlier environment?
