This is the plan network guys provided us, could you please see if this approach makes sense:
We have 2 CP in one DC and 2 CP in other DC - Active/Passive deployment. Currently sync link is on a sync interface (Sync interface and Switch port 1/0/42), and it is planned to introduce additional interface in Bond :
#1 Connect the cables upfront - interface in shut
#2 Move all the VSXs to one DC (Data Center).
#3 Configure interface eth - 2/07 on CP as a bonded interface;
#4 Remove/Shut settings from old Sync:
#5 Enable/Unshut eth - 2/07 (on CP) and eth 2/0/42 (on Switch);
#6 Check if interfaces and port-channel (Bond) come up;
#7 Reconfigure Sync and 1/0/42
#8 Check bond is up with 2 interfaces
#9 Sync the firewall
Does it make sense was how to perform the backup before this intervention, VSX or complete backup?
