I have a customer who has 1 unity 4.2.1 with exchange 2000 (no failover) environment and Unity is in its own AD domain as domain controller. Cutomer wants to implement failover for unity.
New message store server will be Windows 2003 OS and thinking about using Exchange 2000 server CD that came with Unity 4.0.5 (upgraded to 4.2.1 lately) and this server will be running AD
1. Can I use message store (exchange 2000) cd that came with unity to install exchange 2000 on new windows 2003 server platform?
2. I know I can seperate exchange from unity server but can I demote existing unity server from being Global catalog and domain controller and configure new exchange server for AD?
3. What migration path do I need to use it?
