6509 MSFC Sup1A firmware upgrade/downgrade

We just replaced a Supervisor Sup1A module in a 6509. However, the new module MFSC IOS doesn't match the other sup module inside the 6509. I know that both MFCS need to be identical concerning software. Can anyone point me to a document that tells me how to get this done.

Thanks

Hi Jojo,

In dual router mode, the MSFCs are independent of each other in terms of software upgrades, although you are correct that the IOS version needs to match. So, the standard MSFC upgrade procedure is all you need:
