In the field we're not enumerating all the parameters and checking the differences. It is actually helping to getting a consistent state across the two products.
If Jabber/ASA/XMPP proxy was involved and it was large enterprise 25k plus users multi-cluster I would spend the time. Sub-1000 we don't get into that level detail.

Unfortunately, I have been down the path of enumerating all parameters on CUCM <http://cisco-voip.markmail.org/search/?q=holloway%20parameters%20sql#query:holloway%20parameters%20sql+page:1+mid:spbnktjt3fkxoguk+state:results>, and it isn't pretty. Are you, or engineers you know actually noting the parameters before and after and furthermore running a diff on the two? I cannot believe this is actually happening in the field. Your comment of "Generally it is a non issue when dealing with those parameters." is what I suspect most people are going to say/think/feel about this. For the record, I am targeting 10.5(1)SU1, but Cisco running true to form, the latest Upgrade Guide available is for 10.0(1).
