Applies to: Exchange Online, Exchange Server 2016

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the Stop-MigrationBatch cmdlet to stop the processing of a migration batch that's in progress.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Stop-MigrationBatch [-Identity <MigrationBatchIdParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Partition <MailboxIdParameter>] [-WhatIf [<SwitchParameter>]]

This example stops the migration batch that's currently being processed by the migration service.


This example stops the migration batch MigrationBatch1.

Stop-MigrationBatch -Identity MigrationBatch1

The Stop-MigrationBatch cmdlet stops the migration batch that's being processed in your on-premises Exchange organization or by the cloud-based migration service running in Microsoft Office 365. You can only stop migration batches that have mailboxes that are still in the process of being migrated or are waiting to be migrated. Stopping a migration won't affect mailboxes that have been migrated already. The migration of mailboxes that are being actively migrated is stopped immediately. If all migration requests in a migration batch are completed or failed, this cmdlet won't run.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Mailbox move and migration permissions" section in the Recipients Permissions topic.


Parameter Required Type Description




The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




This parameter is available only in on-premises Exchange 2016.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example,




The Identity parameter identifies the name of the current migration batch. The value for this parameter is specified by the Name parameter of the New-MigrationBatch cmdlet.




This parameter is reserved for internal Microsoft use.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
