Running different versions of SCLM in multiple partitions

When you upgrade to a new version of SCLM (or apply a PTF), if you have two or more partitions running different versions of SCLM accessing the same SCLM project, you must:

Ensure the SCLM project definition load modules are assembled using the earliest version of the SCLM macros.
Upgrade the various partitions as required.
After all partitions have been upgraded to use the new version of SCLM, assemble the SCLM project definition using the new SCLM macros.

Note:

You cannot utilise the features in a new version of SCLM (or PTF) until all the partitions accessing the SCLM project have been upgraded to use the new version of SCLM.
In the past, if you had different partitions running different versions of SCLM, you may have experienced problems when upgrading SCLM. To get around this, a process was developed to upgrade an existing SCLM project definition to that of the version of SCLM you were running. However, if you assembled the SCLM project definition using z/OS® 1.9 macros and then attempted to access them using a z/OS 1.8 (or earlier) version of SCLM, SCLM generated the message "FLM81204 - - ERROR INITIALIZING THE PROJECT DEFINITION".
