We are TSS r15, z/OS1.13 preparing for 2.1. We were still on r14 when we upgraded to 1.13, we were forced to add uid to acids doing ftps but the OMVSGRP(DFLTGRP) was still being utilized for the gid. When we move to 2.1, we will need to connect acids to a group with a gid. Is there any issue using the same group for user acids and process ids that are currently using this default gid? Do you have any recommendations on how to proceed?
