Domain Controllers Down for Data Center Move

[askraydotcom]

Hi,

We have Unity 4.0.4 and will be moving components of our data center this weekend. The Global Catalogue and Domain Controller servers will be down for about 5 hours but our MS Exchange message stores will be up. Does anyone know if this will pose a problem for Unity? Any Unity preparation suggestions, (aside from backups)?

Thanks

This will pose a problem for both Unity and Exchange. Exchange is very dependent on the AD infrastructure (DCs, GCs) and Unity is very dependent on Exchange. Unity does have the concept of the UMR (see link below). The UMR temporarily stores new messages in the \CommServer\unityMta folder while the partner Exchange server is offline. When it comes back online, the messages in this folder are moved to the Exchange server.

Hope this helps. If so, please rate the post.

Unity 4.0 is wholely dependent on Active Directory to function properly.

I looked for some documentation on cisco.com and found this that alludes to the importance of AD (DC/GC) for Unity's proper operation:

To prepare, I would recommend initiating a manual synchronization via the DC/GC Reconnect tool (found in Unity Tools Depot) before the DC/GCs are taken off-line and also informing everyone who has a vmail box on the Unity server that vmail will not function during the timeframe of the DC/GC move.

I hope this helps.
