Upgrading from ACS 3.3 to ACS 4.0

[amorielljr]

I currently use ACS 3.3 to authenticate all of my VPN users, my router and switch AAA, my Ciscoworks LMS users, and my Ciscoworks VMS users. I have performed the upgrade to ACS 4 in the lab on a very limited basis (I just tested the router and switch AAA after the upgrade). I was wondering if anyone else has run into any problems after the upgrade.

TIP: always do a backup before upgrade - if it goes pear shaped you can revert straight back to the previous version.
