Replacing Edge GW with PfSense

Hi all,

i'm just join this forum to ask a question about migration in my cloud; i'm a newbie.

I have an Edge gw and a pfsense vm, both share the same routed networks.

I need to translate the routed networks into isolated networks and keep only the pfsense vm.

preparing for  this operations, i think it's required

1. shutdown all the virtual machines

2. create an isolated network

3. unlink the routed network from all vm

4. delete routed network

5. link all the vm to the new isolated network

6. start the vm

have you any suggestions/precutions, GURU's?

thanks!!!
