How to Upgrade an Arcserve Cluster-aware Environment to this Release-IMPW

You can upgrade Arcserve Backup to a cluster environment with job failover capability on the following cluster platforms:

• Microsoft Cluster Server (MSCS) in x86/AMD64 Windows Server
• NEC CLUSTERPRO/ExpressCluster X 2.1 for Windows
• NEC CLUSTERPRO/ExpressCluster X 3.0 for Windows
• NEC CLUSTERPRO/ExpressCluster X 3.1 for Windows
• NEC CLUSTERPRO/ExpressCluster X 3.2 for Windows
• NEC CLUSTERPRO/ExpressCluster X 3.3 for Windows

To upgrade an Arcserve cluster-aware environment to this release

1. Upgrade Arcserve Backup using one of the following procedures:
   • Upgrade Arcserve Backup from r12, r12.5, r15, r16 to r16.5 in an MSCS Cluster Environment.
   • Upgrade Arcserve Backup from r12, r12.5, r15, r16 to r16.5 in an NEC CLUSTERPRO Environment.
2. Verify the upgrade.
3. (Optional) Arcserve Backup does not support recovering the Arcserve Backup database when the last backup of the Arcserve Backup database was completed before you upgraded to this release. As a best practice, you should back up the Arcserve Backup database as soon as possible after the upgrade is complete. For information about backing up the Arcserve Backup database, see the Administration Guide.
