I am planning for an VSS in Core but firstly I need to upgrade FWSM which is at 3.2 Ver to 4.0.4 (min release) I have checked software dependencies

but not sure about Hardware Dependency  on Fwsm and Chassis for Eg. Rommon Upgrade on Chassis. Please help in this regard.

Dear Mike,

Thanks for the rply but currently i am running 12.2(33)SXH2a on my Core 6509 and the link you sent i have referred it earlier but it states only I-Train of IOS while mine is H-Train so can I directly upgrade to I-Train or I was thinking of SXH8b IOS.

Pls suggest any stable IOS for Core as well as Fwsm 4.0 or 4.1 as this is basic prerequisite for VSS.

Hi Amol,

The FWSM can only store one image in flash at a time, so there is no need to delete anything before the upgrade.

Dear Mike,

Does that mean it will get installed in cf:5 without touching existing cf:4 image.

Also i have read we have to upgrade both Fwsm in a single activity can we upgrade one at a time by breaking sync between both.Pls suggest.

Pls share best practices for upgrading FWSM IOS
