cluster switch upgrade backout plan for CN1610,NX5596 and Nx3132

[Sudireddy]

I am upgrading the cluster switches for the models CN1610,NX5596 and Nx3132.

I am looking some help in back out/downgrade plan if required

I can only speak to the CN1610 as that's what we use. Our rollback plan (which we've never had to use) is the following:

1. Enter the command boot system backup to make the backup image the active image.
2. Enter the command write memory.
3. Enter the command reload the reboot the switch.
4. Enter the command show version and show bootvar to verify you've reverted back.
