We are running Unity 4 & plan to upgrade to Unity 5.0. I have the following questions:
1-> In the current setup, Exchange 5.5 is on the same box as Unity 4 & it's separate from AD, i.e. the Unity domain is totally separate. Can we install Unity 5 on an existing Exchange 2003 cluster & integrate it with AD?
2-> We also plan to integrate with Unified Messaging System, hence we need to install Unified Messaging Gateway 1.0 , correct. For that, is AD integration a must?
