Migrating Backed Up Data to an Existing NAS File Server

You can migrate the backed-up data of a NAS file server to a different, existing NAS file server.


  1. From the navigation pane, go to Protect > File Servers.

    The file servers Overview page appears.

  2. On the File Servers tab, in the row for the NAS file server, in the Name column, click the NAS file server that has NFS share that you want to migrate to (the destination).

    The NAS server page appears.

  3. In the Protocols table, click NFS.

    The NFS page appears.

  4. In the upper-right corner of the page, click the action button action_button, and then click Migrate to this server.

    The Migration details dialog box appears.

  5. From the Source server list, select the NAS file server that has NFS share that you want to migrate (the source).


    The source server list does not display deconfigured clients. If the source server is already selected for migration, it will not be listed until the migration is complete.

  6. For Date and time of cutover, enter the date and time when you want to complete the migration, initiate the last phase (migration workflow), and email the cutover approver.

    An email is sent to the cutover approvers to approve or deny the cutover. If the cutover approver denies the cutover, then you must reschedule the Date and time of cutover.

    If the cutover is approved, the following things occur:

    • Data aging on the source server is disabled for 90 days.

    • Backup and archive activity on the source subclient is disabled.

    • Backup activity on the destination subclient is enabled.


      After the cutover is approved, you cannot modify or reschedule it.

  7. In the Cutover approver(s) box, enter the users and user groups that you want to approve the migration.

  8. From the Access node list, select an access node to use for the migration.

    If you are migrating an NFS share, only UNIX access nodes are available for selection.

  9. In the Target data starting path box, enter the share name or the volume name, without the server path, to store the migrated source data and source directory structure in.

    To configure multiple shares for migration, you need to select a subclient and complete the migration, and then configure migration for the next subclients that you select.


    After you specify the path, the only way to modify it is to cancel and then re-initiate the migration.

  10. If you do not want to create the backup sets and subclients that the source NAS file server has, then move the Migrate configuration toggle key to the left.

  11. In the Restore type, specify whether to restore the ACLS and the data or only the data.

  12. Select the content to migrate.

    The subclients of the source servers are listed. You can select the checkbox for the subclient that you want to migrate.

  13. Click Save.

What to Do Next

In the Migration status section of the destination NAS file server page, you can do the following:

  • Monitor the progress of the migration.

  • Edit the migration.

    You can select or deselect content paths for migration. If you deselect all the content paths of a subclient, then the subclient created for migration will have no paths.

  • Cancel the migration.


After the migration is complete, the migrated NAS file server data with NFS share is in the location that you specified in the Target data starting path box, and follows the retention criteria of the source subclient. On the destination NAS server, the backupset name is appended to the source server name in the following format:\\source_server\backupset.

The subclient that is created as a part of migration on the destination NAS server has properties such as storage policies, retention, and archiving rules that are similar to the properties of the source subclients.
