How to Upgrade an ARCserve Cluster-aware Environment to this Release

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

• Microsoft Cluster Server (MSCS) in x86/AMD64/IA64 Windows Server
• NEC CLUSTERPRO/ExpressCluster X 2.1 for Windows
• NEC CLUSTERPRO/ExpressCluster X 3.0 for Windows

To upgrade an ARCserve cluster-aware environment to this release

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