Exchange 2010 Edge role on FTMG, to decom FTMG

We have an Edge transport role enabled on the FTMG servers, and the FTMG servers are going to be decommissioned and Checkpoint firewalls to take over. The Checkpoint firewalls will take the FTMG IP addresses. What I need advise on is,

- Can we create an Edge Transport server role in a virtualised environment?
- Can we still use the same physical servers with the FTMG removed and configure with new IP addresses?

Exchange environment:
2 X MBX servers
2 X HT servers
2 X CAS servers
2 X FTMG servers with Edge role enabled.

Please advise as I do no have much knowledge about the Edge transport role, only that it routes Internet emails and protects the organization from viruses.

Yes, you can virtualise an Edge role or you could remove TMG (I'd feel more comfortable doing a clean build though).

If you're changing the IP addresses, you'll need to recreate your Edge subscription (if you keep the server name the same, you won't need to remove the old one).  There's a decent guide on Exchange Server Pro.  If you're replacing multiple Edge servers, you can at least do them one at a time so that you can confirm that mail flow is working through the new server before you replace the other(s).

Thank you Chriskelk. I've confirmed that our DMZ doesn't cater for virtualised systems and that I will have to rebuild the 2 "FTMG servers" with only the Edge role enabled.
Thank you so much.
