ITD is beginning the process of scheduling agency migrations from Exchange Server 2010 to Exchange Server 2013. Starting late January 2016,  ITD will be contacting agency IT Coordinators to schedule migrations on a per agency basis with the goal of completing all migrations by the end of March, 2016. ITD currently does not have plans to move to Exchange Server 2016.


Exchange Server 2013 enhancements are primarily limited to administration, including: EMC (Exchange Management Console) replaced with a Web-Based Exchange Administrative Center; the number of Server Roles is reduced to two( Client Access Server and Mailbox Server Role); and improvements to high availability features and manageability.

End users will notice a redesigned Outlook Web Interface (OWA) with support for offline access, as well as three different UI layouts optimized for desktops, phones, and tablets. In-Place eDiscovery, a feature that allows users to perform a single search across Exchange, SharePoint, and Lync, will not be available at the time of migration. However, it may be available at a later date, at which time a message would be sent to all IT Coordinators.

The Migration Process

Mailbox moves will be scheduled with each agency prior to migrating. Agency Exchange user mailboxes and Exchange resources (-Adm, -Rm, -Equ) will be moved. Although the migration process is scheduled with agencies, ITD will perform the actual work. Agency IT staff should not have to commit resources to this process beyond working with ITD to schedule the migration and answering potential user questions.

Users will continue to have access to their email throughout most of the upgrade process. Towards the end of the process users will be locked out of their mailboxes and will not be able to access them via the desktop client or web app. During the brief period that each mailbox is inaccessible, any new messages will be queued for delivery. 

If Outlook is open when a user's mailbox is upgraded, they will receive a prompt to close the application. The migration will continue on the mailbox. After the migration is complete, it may take up to an additional half hour for Outlook to find the mailbox moved to Exchange 2013 and connect. Outlook Web App (webmail) should be available immediately after the migration. If a user experiences issues after the migration, instruct them to restart their computer and try using Outlook again.

It is recommended that, if users do not need to work during the migration, they should close Outlook to help reduce potential errors with the migration.
