I have recently posted a few rants on the woes of upgrading to and dealing with Yahoo! Panama. This post will take a step off of the soapbox and attempt to seek some genuine help!

I have a rather large YSM account (just over 2000 keywords) that is ready for upgrade to Panama. This will be the 4th account I've migrated over, but this will in fact be the largest undertaking to date. I've read all the information Yahoo has to offer on the subject of 'preparing your account' for the upgrade. To avoid having your account massacred by the upgrade process, YSM suggests breaking your categories up into smaller groups that are more relevant to each other. This supposedly eases the process into the Campaign/AdGroup organizational structure.

Does anyone have any tips on an easier solution to this problem for a large sized account? The upgrade preview for this account is a disaster. With YSM's reconstruction, I lose an already successful organization of my account. I'm open to any and all suggestions.
