I need to upgrade the appliance 2200 from single FW to Cluster and management resides on the same box. Existing fw is on r75.40 and new one is on r77.30. We cant have much downtime other than for swapping the box. The plan is to configure the new 2200 on r77.30 send it to the remote site and swap the hardware. Bring back the old 2200 and configure it as secondary and ship it out the remote site.
. I am not sure how to do replicate the config from old box to new one. Never done this before.
