Prep for GTM Upgrade or Change

[guru]

There has been a few times when an upgrade broke an application but I didn't know since logs looked good and everything appeared to be good.

So now I run a before (B4) and an after test and then I compare to get more details on status changes and what is affected vs just knowing the number of available WideIPs isn't the same.
