Is it possible to validate this information:<br><br>On the Cisco website it makes mention tthat the Unity 2.4.X veriosn can NOT be installed on an Exchange 2000 server nor in an existing Exchange 2000 environment.<br><br>http://www.cisco.com/warp/customer/788/AVVID/unity_exchange2000.html<br><br>http://www.cisco.com/warp/customer/788/AVVID/unity_win2k_member_server.html<br><br> <br><br>My customer has the following situation:<br><br>He is using a server with Unity 2.4.6 and Exchange 5.5 which is connecting/interconnecting to their corporate e-mail Exchange 5.5 server and he is using VMO.<br><br><br>The customer has migrated from NT4.0 to Windows 2000 and he wants to also perform a migration of his Exchange server from 5.5 to Exchange 2000 for his corporate e-mail server.<br><br>Thus if the information mentioned on the Cisco site is correct, we would have to plan a migration of Unity to 3.X version in order to be able to perform a migration of Exchange 2000, for both the Unity and the corporate e-mail server?<br><br><br>
that's correct. Unity 2.x can't talk with Active Directory and can't log on to Exchange 2000 mailboxes among other things. You'll need to upgrade to Unity 3.x if you want to continue using unified messaging with Unity.
Jeff, I know Cisco supports 2.4.x in Mixed-Mode (defined as PDC upgraded to Win2K AD, BDCs still NT 4). What about support for Win2K Native Mode with PDC Emulator? I am being asked to review configuration for a customer who wants to upgrade their domain to AD and eliminate NT 4 DCs. Will PDC Emulator continue to provide the functionality required for 2.4.x based systems?
