We've been running 2 6500, supervisor 1a/pfc/msfc for some years and as the network have grown, we bought 4 supervisor II, pfc2, msfc2 (no budget for Sup720 for now). I'm looking for hear from people who made this conversion for any tips they have.
The first difference we've found is the limitation in the number of HSRP groups (256 in Supervisor 1 and 16 in supervisor 2, sigh!).
If there are some thoughts, reports, regrets :-), etc, I will be glad to hear from you.
Thank you. Antonio
