Upgrading an existing CASO managed media server

The central administration server must be upgraded before any managed media servers are upgraded.

See Upgrading an existing CASO installation.

Before upgrading Backup Exec, run a database maintenance job to delete job histories and catalogs that you no longer need in order to shorten the upgrade window.

See Configuring database maintenance.

To upgrade an existing managed media server

Verify that the latest service pack for Backup Exec 12 is installed.
Pause the managed media server to prevent the central administration server from delegating jobs to it. If jobs are running, let them finish or cancel them before beginning the upgrade.

See Pausing and resuming a managed media server in CASO.
On the managed media server that you want to upgrade, do one of the following:
- Choose where to keep the device and media data.
  
  See Installing a managed media server from the central administration server in CASO .
- Keep the managed media server's device and media data centralized on the central administration server. To move the device and media data to a database on the managed media server at a later time, you must run a separate application called Backup Exec Utility. Backup Exec Utility will prompt you to retarget jobs and media server pools to use the new device and media data location on the local managed media server.

Resume the managed media server.
