The High Level Qualifier for the Files Data Set Log Files should be changed from DMS1 to DMS2..
Is it possible to simply rename the existing the Log Files and and just change the FILOGNAME SYSPARM accordingly or is anything else required like DMSAR=REMOVE/INSTALL?
Nothing else is required. Just rename the Log files and update the FILOGNAM SYSPARM.
NOTE: the FILOGNAM SYSPARM is not stored in Storage and it is read everytime from the SYSPARMS, when DMSAR or a CA DISK Batch job is running.
For this reason a DMSAR=REMOVE/INSTALL is not necessary.
