Be careful when installing the CPS Protection Agent on the servers that have older versions of Remote Agent installed. The CPS installer can optionally upgrade the Remote Agent components. However, this upgrade breaks existing backup functionality if the Backup Exec Media Sever is a 11d or earlier version. The installer will always alert you before upgrading the Remote Agent. The same consideration should be given when upgrading Backup Exec if that is where the Continuous Management Service will run.
