I am in the process of starting a Datacom version 14.0 to 15.1 active MUF upgrade process.
Where are the new 15.1 CUSPROC , CUSMAC and CUSLIB datasets allocated?
The 15.1 CUSMAC, CUSLIB and CUSPROC datasets are allocated and populated when running BDCUSACT.
This task needs to be performed for each MUF being upgraded because the group of data sets and their contents are unique to a specific MUF.
For more details on this active MUF upgrade , see Upgrade from Version 14.0 to 15.1
