I hope somone can assist in my dilemma.
I have a customer that is currently runnning Unity 7 (no failover), with a partner server (exchange) running 2003.
The customer is looking to upgrade their 2003 Exchange partner server to Exchage 2007.
I have reviewed the Unity 5.x documentation, but am only really seeing guidance on a new install (of Unity) and the declarations for OAB for "lgeacy clients". On Exchange 2007.
This I understand, but I am not sure what the proper prgression would be for Unity to incorporate itself into the new Exchange 2007 environement. I have installed NEW Unity 7 into 2007, but never when the partner server upgrades and that's it. Can someone assist?
This is the link you probably need:
This is part of the Unity 7 upgrade guide, specifically how to change partner exchange server.
As a general approach, I would rather build a new exchange server and then migrate the user profiles over rather than simply upgrade the existing exchange - this method gives some rollback cover both for exchange and unity.
