I have not installed 3.2 manager, or implemented, or upgraded any system to 3.2, so this converstaion is very interesting. I am figuring I will wait until you guys beta test 3.2 before I move from the cutting edge to the bleeding edge.
I still think I would follow the upgrade path to 3.1.65 including the intermediate upgrades when needed. Then upgrade to 3.2, just because it would seem to be less reliant on the unseasoned 3.2 manager.
I do not upgrade except to fix known issues with the current release features that are in use, or to add desired features from the new release.
Am I too cautious? I have found some upgrades have some nice fixes, and some painfull breaks built in.
You do not always get what you pay for, but you never get what you do not pay for.
