I just purchased 2 new servers. Both will be running Windows Standard 2012 R2. One will be used to run Exchange 2013 HUB/CAS (LAN) and the other will be a Web server (DMZ) hosting various internal websites (IIS/PHP). Instead of having a 3rd older server run Exchange 2013 Edge, I was thinking on installing it on the new Web server. Any disadvantages or no-nos?
Thanks
