I've got a WS-X6748-GE-TX that i want to put into my 6509 Sup720 system. I need to upgrade the IOS for the system to be compatible with the module.
I've got dual Sup720s running RPR+ at the moment. The question is, can I install the 6748, upgrade the standby module, reload it so it boots up with the new module in place (while the primary stays up on the old version). Then when i'm ready for my scheduled downtime, cut over to the standby as the new primary, and upgrade the old primary?
Or is all this asking for trouble?
