Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Move-DatabasePath cmdlet to set a new path to the location of a database on the specified Mailbox server and to move the related files to that location.

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

Move-DatabasePath -Identity <DatabaseIdParameter> [-ConfigurationOnly <SwitchParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-EdbFilePath <EdbFilePath>] [-Force <SwitchParameter>] [-LogFolderPath <NonRootLocalLongFullPath>] [-WhatIf [<SwitchParameter>]]

This example sets a new path for the mailbox database specified by the mailbox database name. To perform the move operation, the database must be temporarily dismounted, making it inaccessible to all users. If the database is currently dismounted, it isn't remounted upon completion.

Move-DatabasePath -Identity MyDatabase01 -EdbFilePath C:\NewFolder\MyDatabase01.edb

When you use the Move-DatabasePath cmdlet, consider the following:

  • This cmdlet fails if it's run while the database is being backed up.

  • If the specified database is mounted when this cmdlet is run, the database is automatically dismounted and then remounted, and is unavailable to users while it's dismounted.

  • This cmdlet normally can be run on the affected Mailbox server only. An exception is that this cmdlet can be run on an administrator's workstation when using the ConfigurationOnly parameter with a value of $true.

  • This cmdlet can't be run against replicated mailbox databases. To move the path of a replicated database, you must first remove all replicated copies, and then you can perform the move operation. After the move operation is complete, you can add copies of the mailbox database.

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 databases" entry in the Recipients Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the GUID, distinguished name (DN), or name of the database.




The ConfigurationOnly switch specifies whether the configuration of the database changes without moving any files. A value of $true changes the configuration. A value of $false changes the configuration and moves the files. The default value is $false.




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.




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, dc01.contoso.com.




The EdbFilePath parameter specifies a new file path for the database. All current database files are moved to this location. The default location is <ExchangeInstallDirectory>\Mailbox\LocalCopies\MBDatabase.edb. This file path can't be the same as the path for the backup copy of the database.




The Force switch specifies whether to suppress warning or confirmation messages. You can use this switch to run tasks programmatically where prompting for administrative input is inappropriate. You don't need to specify a value with this switch.




The LogFolderPath parameter specifies the folder where log files are stored.




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.
