<div class="">We are looking at ways to make upgrades easier and stories like these are very helpful.</div>

<div class="">1. I'm guessing we are 10% True bugs and 90% environment, but I will agree with other comments about DNS and NTP being a dumb reason to fail </div>
<div class=""><br class="">
</div>
<div class="">2. as for time, over the years we used to spend over 6 months on upgrades...... we are down to about 2 months. in our enviroment we have to document all the changes before so it can be communicated to the end user. Researching for the answers
has moved from Anthony's 100 documents to just opening a TAC case. It has become way to time consuming to find all the right doc's to get the correct answer.</div>

<div class="">Already I can see this is going to be a wide gap in responses. Partner vs end user, this customer vs that customer, this version vs that version, this scenario vs that one, and on, and on, and on.</div>

<div class="">1) I feel like it's always a bug (100%), in that, developers should code solutions that can work around most issues. E.g., I had an upgrade fail on a CUCM because the ntp was
<a href="http://0.us.pool.ntp.org/" target="_blank" class="">0.us.pool.ntp.org</a>, despite CUCM happily syncing to it in the current version. OR Common partition not having enough space, when devs could just purge old logs to make room, or simply make better
logs to begin with (I do admit, moving to compress logs [TAR/GZ] was sweet)</div>
<div class=""><br class="">
</div>
<div class="">2) This is a painful one for me, but I put in a lot of time preparing for an upgrade. A large portion of the time is, in my opinion, wasted finding the right documentation and then trying to interpret it. Here's a fun one: there's over 100 documents
an Engineer needs to reference in preparation for what I would consider a low-medium level environment. I've posted this before, but I'll post it again, I have a matrix of documents I need to reference during the planning and execution phase of an upgrade:</div>

Quick 2 question poll, feel free to unicast or share your response with the group.<br class="">
<br class="">
1. When you or your customers have a UCM or IMP upgrade fail, what percentage of failures are due to a bug vs something in the environment (user error, db updates, etc)?<br class="">
% bug:<br class="">
% not a bug:<br class="">
Yes it’s a very subjective question but that’s ok, use your judgement.<br class="">
<br class="">
2. When an upgrade goes smoothly with no issues, how much time do you put into the planning and preparation for the upgrade (not the execution)?<br class="">
<br class="">
Thanks,<br class="">
