Recommended way to rename assignment groups


I need to rename an assignment group which has many dependencies (Incidents, Requests, Change management, CI's... etc). I know that if I rename the assignment group manually through rad debugger it wont update the dependencies. Each ticket in the system will need to be updated individually. If I delete the existing group and replace it with the new one, I believe only 2 modules will be transfered to the new group. Is there any funcationality to do this (or another recommended way) in sm 941? The issue is there may be other dependencies like in rulesets, etc. If this all has to be updated manually, How do I find and update them?
