[cisco-voip] How Many Docs Does it Take to Prep for an Upgrade?

[Anthony Holloway]

Does anyone else do this?  Gather all of the documentation ahead of time,
because inevitably you're going to revisit a document more than once?
There are a lot of documents to gather!  Anything I could be doing better?
Tips?  Tricks?

I create a spreadsheet of all of the pertinent documents I need to review
or reference, like in this screenshot.  There's over 90 documents in this
list.  Granted, I don't read them all front to back, but some I do, and
 for others I need to reference information within them nonetheless.  You
never know when you might find a small font hidden note in there.

E.g., From the 8945 Release Notes

*"Release 9.4(2)SR1 can only be upgraded from 9.3(4) and later. Releases
prior to 9.3(4) have to be upgraded to 9.3(4) first."*

*Source: 8945 9.4(2)SR1 Release Notes

I actually missed this one recently, and unlike 7900 series phones, they
phone will just brick itself and never register.  Causing you to walk to
every phone and reset power to it, or walk the mac address tables of your
layer 2 network and shut/no shut the ports.
