CommCell Migration - Getting Started

The following steps describe the process involved in migrating the metadata of an entire CommCell to another CommCell.

  1. Export Metadata from the Source CommCell
  2. Import Metadata on the Destination CommCell
  3. Register Migrated Clients

Note that in the following procedure the source CommCell is referred as prodcs and the destination CommCell is referred as prodcs01.

Export Metadata from the Source CommCell

When performing CommCell Migration you will first need to export the metadata associated with the source CommCell. The export operation is performed on the source CommCell, allowing you to select entities that you wish to export from a source CommCell to the specified export location.

Use the following steps to export metadata from the source CommCell:

  1. From the CommCell Browser, right-click the <Source CommServe>, point to All Tasks | CommCell Migration and then click Export To Folder.
  2. By default, Use Local is selected to export location in the local path.

    Click Use Network to export the metadata files on network location.

  3. In the Export Folder specify the network path.
  4. Click User Name/Password to enter the user account information for accessing the network path.

    Select the Use This Account check box.

    Type the user name in the User Name box.

    Type the password for the user in the Password box and re-type in the Confirm Password box.

    Click OK to close the Change User Account dialog box.

  5. Under Select Associations, select the components (for example, Clients, Subclient Policies so on) for migration.

    If you want to migrate a client that has Virtual Server Agent installed, select both the client and the virtualization client.

    Click OK to export meta data.

  6. You can track the progress of the job from the Job Controller window of the CommCell console.

Import Metadata on the Destination CommCell

The metadata associated with the client in a source CommCell can now be temporarily imported on to the destination CommCell. The import will use the import entries that you have defined for the destination CommCell.

Use the following steps to import metadata of a source CommCell to destination CommCell:

  1. Log on to destination CommCell.
  2. From the CommCell Browser, right-click the <Destination CommServe>, point to All Tasks | CommCell Migration and then click Import From Folder.
  3. In the Select Import Folder page, select one of the following and then click Next.
    • If you have copied the exported source metadata on the local drive of destination CommServe, then select Use local and specify the local path in the Import Folder box.
    • If you have exported metadata on network path, select Use Network and specify network path in the Import Folder box.

      Click User Name Password and provide the user credentials to access the network path and then click OK.

  4. Under Select CommCell,select the source CommServe to import and click Next.
  5. From Specify MediaAgents that have read access to the mount paths and edit access paths if needed wizard, specify the following:
    • By default Destination MediaAgent is set to Not Accessible. Use Not Accessible option if:
      • You do not want to perform any restore operations on migrated clients.
      • You are migrating MediaAgents permanently which have access to the migrating library.
    • Select MediaAgent from destination CommCell to access the migrating library for restore operation.
    • From the Select MediaAgent for Index Restore list, select the MediaAgent from the destination CommCell.

      Once specified the MediaAgent accesses the index from the migrated library and stores it in the index cache folder. This is useful for restore operation.

    Click Next.

  6. Enter a new name for the client if required. If nothing is specified the old name will be used and then click Next.

    If you want to change the client name during migration, we recommend you specify both the client host name and the client name.

  7. Review the selected import options and click Next.
  8. Accept the default options for first import operation and then click Next.
  9. By default, Immediate is selected to start the import process immediately.

    Alternatively, you can schedule the import job for a later time.

    Click Finish to complete the import operation.

  10. You can track the progress of the job from the Job Controller window of the CommCell console.
  11. Components selected for export on the source CommCell will be imported on the destination CommCell.

    Note that the migrated clients will appear as deconfigured clients and will be available for cross machine restore on to local clients.

    To perform backup operations on these clients, you must permanently migrate them to the destination CommCell by applying licenses on these clients. The migrated clients will appear as uninstalled clients.

Register Migrated Clients

Perform registration of migrated clients if you want to permanently migrate clients to destination CommCell.

To migrate a CommServe client, refer Migrating a CommServe Client for the instructions. Ensure to migrate all other clients before you migrate the CommServe client.

If the migrated client is behind a firewall, ensure to configure and push the firewall settings from the destination CommServe to the migrated client. See CommCell Migration - Configuring Firewall Settings for more information.

If you do not want the destination CommServe to connect to the source CommServe during name change of the migrated clients, then, certificates will not be applied automatically on the migrated clients. You must manually apply certificates on the migrated client, else name change operations will fail. See Manually Applying Certificates for more information.

Use the following steps to register the migrated client computer by applying license:

  1. On the new CommCell, navigate to the CommCell Console ribbon and then click Control Panel.

    Under Configure, click Name Management. The Name Management Wizard appears.

  2. Select Update CommServe for Clients (use this option post migration) and then click Next.
  3. Select the old CommServe hostname from which you wish to migrate the clients to the current CommServe.
  4. Click Next.
  5. Select the clients from the Available list and click > to add them to Selected list.

    If the migrated client has Virtual Server Agent installed, select only the client from the Available list. Do not select the virtualization client.

  6. Click Next.
  7. Select the following options in the Select Client Configuration wizard:

    Under Source Options:

    1. By default, the Try to contact Source CommServe check box is selected to access the client information from the source CommServe.

      If you do not want the migrated client to contact the source CommServe, clear the Try to contact Source CommServe check box. In the Confirmation dialog box, click OK..

    2. If you want to deconfigure the migrated clients and delete the data paths (mount paths) associated with the MediaAgent clients, select Deconfigure the migrated clients on source and remove datapaths.
    3. Select Do not deconfigure migrated clients on source, only disable client activity and datapaths to not configure the migrated clients but:
      • Disables all client activities (such as backups/subclient creation so on).
      • If the client is MediaAgent then disable write operation on the datapaths (mount paths).

      Note that this will not deconfigure the migrated client. You can still perform restore operations from these clients.

    Under Destination Options:

    1. By default, Consume Licenses check box is selected to consume the license for the migrated clients on the destination CommCell.
    2. Select Only proceed if licenses are available for clients to be migrated to consume licenses for the migrated clients if you have sufficient licenses on the destination CommCell.
    3. Select Consume available licenses, migrate the rest as restore-only clients, if you have a few licenses available on the destination CommCell and you wish to consume those licenses for those migrated clients and for rest of the clients you wish to register as uninstalled clients.
  8. Click Next.
  9. On the Confirmation dialog box, click Yes to register the CommServe.
  10. On the Register remote CommCell dialog box, provide the credentials and hostname of the source CommCell. Click OK.
  11. From the Storage Policy list, select the storage policy that you want to store the client backup data. To assign a storage policy for all subclients, from the Change all selected Storage Policies to list, select the Storage Policy and then click Apply.
  12. Click Finish.
  13. Click OK to the Confirmation popup, and then close the Control Panel window.

    The client appears as configured under the Client Computers node if Consume licenses is selected.

    The client appears as uninstalled under the Client Computers node if Consume licenses is not selected.

  14. If you did not select Try to contact Source CommServe, run the script ChangeCSHostNameAfterMigration QScript on the PodCell for all of the selected clients.
  15. Restart the services on the client after the name change. For more information, see Restarting a Service.

If you have migrated a client that is behind a firewall, ensure to push the firewall settings from the destination CommServe to the migrated client. Right-click the migrated client and then click All Tasks > Push Firewall Configuration. Check the readiness of the migrated client. See Checking Connectivity from the CommCell Console for more information.

If you have migrated a client that has Virtual Server Agent  installed, enable backups on the Virtual Server Agent.
