You can use the E-mail Migration dashboard in the Exchange Control Panel to manage mailbox migration to Exchange Online using a cutover or staged Exchange migration. You can also use the migration dashboard to migrate the contents of users’ mailboxes from an on-premises IMAP server to existing cloud-based mailboxes. The migration dashboard displays statistics about the overall migration in addition to statistics about a specific migration batch. You can create, start, stop, pause, and edit migration batches.

The migration dashboard

To access the migration dashboard, select Manage My Organization > Users & Groups > E-Mail Migration. The following screenshot identifies the different areas of the migration dashboard that you can use to get migration information and manage migration batches.

Overall migration statistics

This area of the migration dashboard displays the overall statistics about all migration batches that have been created. The following fields display cumulative information about all migration batches.

Field	Description
Total	The total number of mailboxes from all current migration batches.
Active	The number of mailboxes that are actively being migrated. This number corresponds to the number of mailboxes to migrate simultaneously that you specified when you configured the connection settings for the migration batch that’s currently running.
Synced	The number of mailboxes from all migration batches that were successfully migrated.
Errors	The number of mailboxes from all migration batches for which migration failed.

Note   Depending on the migration type, the value for these fields also indicates the number of distribution groups and mail contacts that were migrated.

Migration batches

Migration batches that are created are listed in the migration queue. The following columns display information about each migration batch.

Column	Description
Position	Indicates the position in the migration queue. Exchange Online processes the migration batches in the sequence listed in the Position column. You can change the sequence of migration batches by selecting a migration batch and then clicking Move to Top or Move to Bottom .
Name	The name of the migration batch that was defined when the migration batch was created.
Status	The status of the migration batch. The following is a list of the different status states for migration batches, along with what you can do with migration batches in each of these states: Created   The migration batch has been created. In this state, you can start, edit, delete, or change its position in the migration queue using or . Queued   The migration batch has been started. If the migration batch is at the top of the queue, it will start to run. If there are migration batches above it in the migration queue, the migration batch will remain in a queued state. It will start running after all migration batches above it have completed. When the migration batch is in this state, you can stop it or change its position in the migration queue using or . Running   Mailboxes in the migration batch are being actively migrated. When a migration batch is in this state, you can stop it. Stopped   The migration batch is stopped, and no more mailboxes from the batch are being migrated. When a migration batch is in this state, you can restart it. Synced   The migration batch has completed, and no mailboxes are being actively migrated. A migration batch in this state may contain errors if mailboxes weren’t migrated. For cutover Exchange migrations and IMAP migrations with this status, on-premises and cloud-based mailboxes are synchronized every 24 hours.
Migrated	Indicates the number of mailboxes (out of the total number of mailboxes in the migration batch) that were successfully migrated. For example, the value 8/10 indicates that eight mailboxes, out of the total migration batch of 10 mailboxes, were successfully migrated.
Errors	The number of mailboxes in the migration batch for which migration failed. You can display information about specific mailboxes that have migration errors. For more information, see E-mail áttelepítési felhasználók állapotjelentései.

The migration dashboard contains a set of commands that you can use to manage migration batches. After you create a migration batch, you can select it and then click one of the following commands. If a migration batch is in a status state that isn’t supported by a command, the command is dimmed because it’s unavailable.

Command	Description
New	Create a new migration batch. If there are current migration batches, the migration type and connection settings persist from the previous migration batch. If no migration batches have been created, you have to select the migration type and then enter new connection settings.
Edit	Edit an existing migration batch. You can change the connection settings for the migration batch and change the number of mailboxes to migrate simultaneously. For staged Exchange migrations and IMAP migrations, you can submit a different CSV file. You can only edit a migration batch that has a status of Created.
Start	Start a migration batch that’s been created. As previously stated, if the migration batch is at the top of the queue, it will start to run. If there are migration batches above it in the migration queue, the status of the migration batch is changed to Queued. Exchange Online will start to process the migration batch when it’s at the top of the queue.
Resume	Resume the running of a migration batch that was paused and has a status of Stopped. If there are errors for a migration batch, you can restart it with this command and Exchange Online will attempt to migrate the mailboxes that failed.
Pause	Stop a migration batch that’s currently running or that’s been started but has a status of Queued. You can also stop a cutover Exchange migration batch or an IMAP migration batch that’s completed the initiation synchronization phase and has a status of Synced. This will stop incremental synchronizations. You can resume incremental synchronizations by selecting the migration batch and clicking Resume.
Delete	Delete a migration batch after you verify that all mailboxes in the migration batch have been successfully migrated and that mail is being routed directly to cloud-based mailboxes after you have configured your MX record to point to Office 365. When you delete a migration batch, Exchange Online cleans up any records related to the migration batch and removes it from the list. When you delete a migration batch for a cutover Exchange migration or an IMAP migration, Exchange Online performs a final synchronization for all mailboxes and then stops synchronizing the on-premises mailboxes and the cloud-based mailboxes in the migration batch.
Move to Top	Move a migration batch to the top of the queue.
Move to Bottom	Move a migration batch to the bottom of the queue.
Refresh	Refresh the migration dashboard to update the information displayed for the overall migration statistics, the list of migration batches, and the statistics for the selected migration batch.
