Has anyone had any experience with this application?

We are basically looking to install the 2010 version a.s.a.p as we have a pressing need for it's functionality, however we would also like to "upgrade" to 2010 R2 once it comes out of Beta and into live.

Has anyone tried "upgrading" their 2010 version to 2010 R2 Beta?

Did you have to carry out a fresh install?
Were you able to migrate teh database if you had to reinstall?
Can you update the client on machines or does that have to be removed\re-added?

Essentially, if we roll this out now, and we get our users to fill in details for the password management side of things, will they have to do this over again when wego to the next version?
