Many years ago, someone set my company up on a local 132.147.xxx.xxx subnet that is currently configured in our FortiGate (running 6.2). I would like to gradually migrate us off of this. My question has to do with the best path to do it. We currently have FortiSwitches that are in standalone mode. With a LAN interface built for this current addressing scheme. I would like to move us to a new addressing scheme with a 10.16.xxx.xxx VLAN for data and a 10.17.xxx.xxx for Voice as we would like to eventually add VOIP.
Would it be best for me to build this through FortiLink? I have two switches that are not currently being used, that I could start this on. Also, how would I build a path between the old network (132.147) and the new network (10.16) so that I could gradually migrate devices over to the new network, could I just do a policy for both directions? Thanks in advance.
