About upgrading an existing CASO installation

In an existing CASO environment, upgrade the central administration server, and then upgrade the managed media servers.

If necessary, you can perform rolling upgrades in the CASO environment. That is, you can upgrade the central administration server from Backup Exec 12.5 to Backup Exec 2010 first, and then upgrade the managed media servers from Backup Exec 12.5 to Backup Exec 2010 over a period of time. You must have the most recent Backup Exec service pack to perform rolling upgrades.

Note:

Forward compatibility is not supported in rolling upgrades. Therefore, any system that runs Backup Exec 12.5 cannot protect a system that runs Backup Exec 2010.

Symantec recommends that you do not keep a mix of versions in the CASO installation for an extended time. Key functionality for administering managed media servers is missing in a mixed-version environment, and decreases your ability to properly administer the CASO environment.

Note:

If the managed media server has the SAN SSO Option installed, you cannot perform rolling upgrades.

After you upgrade the central administration server to Backup Exec 2010, the following operations are supported on managed media servers that run Backup Exec 12.5:

  • Backup

  • Restore

  • Inventory

  • Catalog
