EVA3k fw upgrade from 3.028 to 3.110

[Nappy_1]

We will do a fw upgrade of an EVA3k from 3.028 to 3.110
I'd like to know how we can do a rollback it the upgrade doesn't succeed

Rollback? I am afraid that means flashing the old firmware and reloading the old configuration and data, because almost every firmware upgrade makes incompatible changes to the internal meta-data and there is no downgrade feature like on the old HSG (to be fair, the EVA data structures are _way_ more complicated).

So, please, please, please:
Before someone does upgrade the EVA firmware:
- make a FULL data backup
- save the old EVA configuration with CAPTURE CONFIGURATION at least.
