<p>2.) I usually devote 16-20 hours of planning and prepping the upgrade (Documentation, Visio, building the bridge if it's that kind of upgrade ... etc). If I have extravagant products in play like Social Miner ... the now defunct MediaSense ... etc, I might
add a little more time but right around the 20 hour mark is where I feel comfortable.</p>

<div class="PlainText">Quick 2 question poll, feel free to unicast or share your response with the group.<br>
<br>
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>
% bug:<br>
% not a bug:<br>
Yes it’s a very subjective question but that’s ok, use your judgement.<br>
<br>
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>
<br>
Thanks,<br>
