[cisco-voip] Exchange 2003 & 2007 co existing in Unified Messaging

[James Buchanan]

I believe when running mixed like that you must have the 2003 server as
the partner server. On the back end, the two servers will communicate
with each other and messages will continue to be delivered without
issue.

 

When you're ready to retire the 2003 server, you'll need to run the
MSCW.

Subject: [cisco-voip] Exchange 2003 & 2007 co existing in Unified
Messaging

 

Hi All

 

I have a customer who is running Unity 5 with Exchange 2003 Unified
messaging, they have built a new separate exchange 2007 cluster and
co-existed it within the same organisation as the Ex 2003 and they are
hoping to migrate users in a staged fashion.

 

Is it going to be possible to add another message store to Unity and
have users on both clusters or will they have to migrate all of the
users in one go and then re run the Message Store Wizard to change the
Partner server to 2007.

 

Just wondering what the best options are to tell this customer as they
have already migrated some users without thinking about the Unity
implications.
