Before an upgrade, we know that we need to back up the configs via CCA. and that we need to back up flash via TFTP... is there a simple command to back up all of flash? or do we need to go line item by line item? and same question on the restore- is there a command to restore all of flash?
We are taking a UC520 customer from XW6 (set up with CCA 1.6 or CCA 1.7) to 20T (using CCA 2.2.1) and we need a disisater recovery plan.
