I'm about to upgrade redEvent and redForm from 1.5.x to v2.0b1 and wondered if there are any tips for this? For example, is there a preferred order to do the upgrades?

I have lots of data in the current versions and want to be extra careful not to lose any in this process. So I'd appreciate anything you can tell me to make it go more smoothly.

Edited to add: after looking at the release notes, I just went in the order they are listed on the downloads page.
