Running earlier versions simultaneously

You can run a previous version of Application Performance Analyzer in the same image. However, each version must use unique started task names, unique STCID, a unique checkpoint data set, a unique SPXGroupName and a unique common data store dataset. Also, use the appropriate version of the Application Performance Analyzer frontend (ISPF and GUI) for any Application Performance Analyzer-started tasks to which you are connecting. When running multiple versions of Application Performance Analyzer in a sysplex, the newest version should be started first.
