Easiest is this way, there will be a minor glitch on failover nr 1:
- copy the interface lines from show configuration interface and adjust inthe following way:
- on the old interface issuing delete interface eth1-03 vlan 25 will delete vlan 25 and all the config from it.
- add the vlan's to the new interface by adjusting the old commands setting the correct interface
- Copy and adjust the set interface ipv4-address commands
- double check those commands make sure to also copy and adjust the set interface state on commands
- on standby member run cphastop to disable clustering
- paste the delete vlan commands
- paste the add vlan and set IP address commands
- now update the interfaces of the backup member in the cluster object, the member interfaces are set in the Advanced tab of the cluster interface configuration
- push policy
- run cphastart on the backup member
- flip the cluster over to the backup member ( this could give a dip in the connections
- now repeat the above steps for the other member
Good luck and be aware to plan this in a maintenance window, easier to tell everyone this will caus 15 minutes downtime and be done in 1 minute than the other way around.
