Migrating a Unified Manager virtual appliance to a Linux system

You can restore a Unified Manager database backup from a virtual appliance to a Red Hat Enterprise Linux or CentOS Linux system if you want to change the host operating system on which Unified Manager is running.

Before you begin

About this task

These steps describe how to create a backup file on the virtual appliance, copy the backup files to the Red Hat Enterprise Linux or CentOS system, and then restore the database backup to the new system.

Steps

  1. On the virtual appliance, in the toolbar click , and then click Management > Database Backup.
  2. In the Management/Database Backup page, click Actions > Database Backup Settings.
  3. Change the backup path to /jail/support.
  4. In the Schedule Frequency section, select the Enable checkbox, select Daily, and enter a time a few minutes past the current time so that the backup is created shortly.
  5. Click Save and Close.
  6. Wait a few hours for the backup to be generated.
    A full backup can be over 1 GB and can take three to four hours to complete.
  7. Log in as the root user to the Linux host on which Unified Manager is installed and copy the backup files from /support on the virtual appliance using SCP.root@<rhel_server>:/# scp -r admin@<vapp_server_ip_address>:/support/* .
    Example
    root@ocum_rhel-21:/# scp -r admin@10.10.10.10:/support/* .
    Make sure you have copied the .7z backup file and all the .7z repository files in the /database-dumps-repo subdirectory.
  8. At the command prompt, restore the backup: um backup restore -f /<backup_file_path>/<backup_file_name>
    Example
    um backup restore -f /UM_9.4.N151113.1348_backup_unix_02-12-2018-04-16.7z
  9. After the restore operation completes, log in to the Unified Manager web UI.

After you finish

You should perform the following tasks:

After you have verified that everything is running as expected on your Linux system, you can shut down and remove the Unified Manager virtual appliance.
