This is achieved by the mailbox synchronization process. During mailbox synchronization, Migration Manager for Exchange gradually transfers the mail data from the source to the target Exchange servers.

All mailbox content, including messages with attachments, contacts, and journal entries, is copied to the target mailboxes. The following tables show details about each type of job. It helps choose the right job type for your purposes:. Table 4: Mailbox Synchronization Job. Table 5: Office Mailbox Migration Job. Table 6: Native Move Job. Exchange Client Access server or Exchange Client Access server if applicable must be deployed in source or target Exchange organization.

Table 7: Legacy Mailbox Synchronization Job. Mailbox synchronization is based on direct copying of data between the source and target mailboxes.

Migration Agent for Exchange makes sure that connections are established to Exchange servers in both organizations and to both mailboxes, and initiates the synchronization. It is a requirement that the target mailbox already exist when mailbox synchronization begins.

The best way to ensure this is to create mailbox-enabled target users during Active Directory migration that precedes Exchange migration. To provide flexibility, the mailboxes to be synchronized are grouped into mailbox synchronization collections. A mailbox synchronization job can handle multiple collections. Collections can be populated by specifying individual users, distribution groups and Active Directory containers.

You can preview a flat list of resulting collection members at any time. During the mailbox synchronization job Migration Agent for Exchange processes the following normal and associated content for each mailbox in a collection:.

As soon as a user's source and target mailboxes are in sync, Migration Agent for Exchange can make the target mailbox the primary mailbox. Mailbox switch can be done either manually from the console see Manually Switching Mailboxes and Undoing Mailbox Switch section of Adding a Mailbox Collection for details or automatically by the agent.

This is configured through options in the collection that the mailbox is in. If you choose automatic switching, you can either schedule the mailbox switch operation for a specified time or have the agent switch each mailbox as soon as it is synchronized.

Automatic switch is recommended because it is not subject to human error. Immediately before switching a mailbox, the agent performs a one-off processing session for the mailbox's Automatic Replies settings also known as Out-of-Office status. This is needed to make sure that any active automatic replies remain active after the switch.

After user's mailbox has been switched either automatically or manually , Migration Agent for Exchange continues synchronizing mail data from the source to the target user's mailbox for a certain time period. This ensures that the most recent messages delivered to the source mailbox after last synchronization was completed but before the mailbox was actually switched are successfully migrated to the target mailbox.

Legacy mailbox synchronization is performed as a separate legacy mailbox synchronization job between each pair of the source and target Exchange servers. To provide minimal stress to the production environment, Migration Manager for Exchange employs the distributed architecture shown in the figure below:.

To provide flexibility, the mailboxes to be synchronized are grouped into mailbox collections.
