We will be installing Exchange 2010 SP1 RU3 on the LOUIE cluster tonight beginning at 9PM Eastern.

During the upgrade on the CAS servers, users may see a brief disconnection while individual CAS nodes are upgraded, however, they should automatically connect to another available CAS server.

During the upgrade on the Mailbox servers, users may see a brief disconnection from public folders while individual Mailbox codes are upgraded, however, they should automatically connect to the next available Public Folder Replica.

During the upgrade on the HUB servers, users may see a brief delay for incoming mail, however, outgoing mail should not be affected.

This upgrade will allow us to seamlessly move mailboxes from LOUIE to our newest Exchange Cluster if partners would like to move.
