This topic describes how to use the Exchange Management Shell to reconfigure a database's file location. In a cluster continuous replication (CCR) environment, there is only a single set of database configuration information that applies to both copies. This creates the additional complexity of needing to relocate both copies. Under some circumstances, one copy may not be available at the time the other copy must be moved.

You can use the procedure in this topic to change the location of a mailbox or public folder database.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and local Administrators group for the target server. For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.

Although we recommend that you perform this procedure when both active and passive nodes are available, it is not required.

Procedure

This procedure performs the following actions:

Changes the configuration
Moves the copy on the active server
Moves the copy on the passive server

To use the Exchange Management Shell to move a database in a CCR environment

Open the Exchange Management Shell, and then halt replay and log replication for the storage group by using the Suspend-StorageGroupCopy cmdlet. To halt replication activities for the storage group, run the following command:
```
Suspend-StorageGroupCopy -Identity <Server\StorageGroupName>
```

Dismount the database by using the Dismount-Database cmdlet:

Dismount-Database -Identity <Server\StorageGroupName\DatabaseName>

Use the Move-DatabasePath cmdlet to change the configuration in the Active Directory directory service. Make sure the database is dismounted prior to performing the move operation. Run the cmdlet as follows:
```
Move-DatabasePath -Identity <Server\StorageGroupName\DatabaseName> -EdbFilePath <NewPath> -ConfigurationOnly
```
Note:
In a CCR environment, you must use the -ConfigurationOnly parameter. The new location must not be the root directory of a volume.
Move the files to their new locations on both the active node and the passive node.
Mount the database in the storage group by using the Mount-Database cmdlet.
Restart replication using the Resume-StorageGroupCopy cmdlet. To restart replication activities for the storage group, run the following command:
```
Resume-StorageGroupCopy -Identity <Server\StorageGroupName>
```
Verify that replication for the storage group is proceeding normally by following the procedures detailed in How to View the Status of a Clustered Mailbox Server.

Note:
In a CCR environment, you must use the -ConfigurationOnly parameter. The new location must not be the root directory of a volume.
