Migrate network object group members; risk

Question

       We upgraded to new 5555 hardware and jumped from 8.2 to 9.1 last year. Our objects listing is now a bit messy. I have never run the "Migrate Network Object Group Members" menu option in asdm. I see what it is going to do, I am not sure it really helps me clean old objects, it seems low risk, but when I walk up to execution, there are a lot of changes it wants to make. We always save backup configurations but, if there are "gotchas" I don't want to put the company in that position. What has been the communities, Cisco's experience? Thanks for any feedback. jc

John,
if you feel that is risky, you can always go for plan B.
- you can take closure look at the object groups and decide new object naming convention policy.
- from ASDM or CSM, you can see overlapped or duplicate rules, so you can start with reducing them
- you can see same services used in couple of rules with different service groups.
     - like object-group service WEB-PORTS tcp
                    port-object eq http
                    port-object eq https
             object-group service APPLICATION-PORTS tcp
                    port-object eq http
                    port-object eq https
               object-group service APPS-PORT tcp
                    port-object eq www
                    port-object eq https
- you can replace all these different object-group with one object group. like WEB-PORTS.
- same way you can do excercise for network group as well.
hope this helps.
