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.
