We are carrying out a firmware upgrade on our 9509’s from 3.3(1c) to 5.2(2) and I want to know if the steps below are correct?
Check hosts for paths to both Fabric's.
Take a backup of the config for all the switches.
On Fabric A upgrade switch 1 to 4.1(x)
Upgrade switch 2 in Fabric A to 4.1(x)
On Fabric A upgrade switch 1 to 5.0(x)
Upgrade switch 2 in Fabric A to 5.0(x)
On Fabric A upgrade switch 1 to 5.2(2)
Upgrade switch 2 in Fabric A to 5.2(2)
When happy, then do the same for Fabric B for the other switches.
Thanks

looks good, just follow the release notes to go to the correct intermediate code level so that upgrade is non disruptive
