Note: We strongly recommend migrating legacy vault data to avoid transferring the initial replication data set over the network. If you skip this migration procedure, the initial transfer requires a tremendous amount of time and bandwidth. After the legacy vaulted data is migrated, only changed blocks are transferred over the network.
1 Verify the following prerequisites have been met:
• All steps in the Prepare source and target systems procedure have been completed.
• The backups device on the target has as much or more free space as the total size of the backups to be migrated. To check free space, select Settings > Storage and Retention > Storage.
• If any encrypted backups on the source will be replicated, encryption must be enabled on the target. See To configure encryption for details.
• If any encrypted backups on the source will be replicated, the source encryption passphrase must be available. You will be prompted for this passphrase when migrating data.
2 Using a terminal emulator, such as PuTTY, connect to the target with the following:
• target system IP address
• port 22
• SSH connection type
3 Log in as a user with root privileges.
login as: root
root@192.168.220.56's password:
4 Enter this command to launch the migration utility:
[root]# /usr/bp/bin/vaultMigration-scripts/mr71VaultMigration.php
5 Preliminary checks are run and messages display. Check the last paragraph on the screen and do one of the following:
• If you see Select the system to migrate..., continue to the next step in this procedure.
• If you see Found some problems..., check for Failed results above in the Preliminary Check list, correct any issues, then rerun the migration utility.
6 In the System(s) list, find the source whose vaulted data you wish to migrate, type its number and press Enter. For example,
Selection (‘q’ to quit): 0
7 Information for the selected system displays. Check the last paragraph on the screen and do one of the following:
• If you see Insufficient space..., note the available space and amount needed. Allocate more space to the Backup/Retention area (Settings > Storage and Retention > Storage Allocation), then rerun the migration procedure.
• If you see Enter to start migration process..., press Enter to begin migration (or type q to quit).
8 If you are migrating encrypted backups, you are prompted for the source’s encryption passphrase. Type in the passphrase and press Enter.
9 While migration is in progress, status messages display.
Note: You can run up to 5 migration sessions to migrate multiple source systems concurrently. Use caution when running multiple sessions as each consumes system resources, which may adversely impact performance. To run another session, start with Step 6 in Prepare source and target systems above to prepare your next source.
10 When migration is complete, you see the message Done, Exiting... and the Linux command prompt returns. For example,
Done, Exiting...
[root]#
If you see any errors, simply rerun the utility to migrate any remaining data. Once the script completes without errors, continue to Upgrade to replication.
