I just transitioned my network from Windows Server 2012 Essentials to Windows Server 2012 r2 Essentials. While following the directions to integrate my email system back into the environment I accidentally installed ARR 3.0 instead of 2.5.
My questions are:
1. Can I install both versions in tandem, or is there a way to uninstall 3.0 and install 2.5?
2. If I cannot install 3.0 then what steps must I take to get reverse proxy working correctly as it should so my users can access their email through the mail.mynetwork.net link they are configured for?
3. Am I totally hosed here?
Thanks in advance for your assistance and attention.
