Hi Steve
Yes, we did it some months ago, when a customer wanted to use Service Load
Balance.
Follow exactly the steps, and also, I would suggest you to open a TAC Case ,
and keep the Cisco Engineer at phone when you do that.
We got some problems with the PCMCIA Flash card at slot 0 , and as this is
not a trivial task , we spent some hours to find when was the problem , and
complete the upgrade on 2 MSFC's.
