Replacing Security Zones

[ihenock101]

Dear Check mates

I have checkpoint R80.40 7K Gateway and I want a topology change previously my firewall external zone is connected to a router and I want to change this physical connectivity to a core switch. For the test purpose I create a new external zone and physically connect the firewall and the core switch and it was successful so I want to migrate the previous zone and policies attached to this zone to the newly created is there any documentation how to do that please?
