In view of the query put forward, it seems that Backup Exec software version is 8.6 and the remote agent which is pushed installed is of version 9.1. We would like to mention you the following.
If you read the software compatibility list ( the technote that you have already referred and link mentioned below, kindly check the following topic "Remote Agent for Windows Servers Compatibility"
http://seer.support.veritas.com/docs/261695.htm
It mentions "While the Backup Exec 9.1 Remote Agent for Windows Servers is recommended for use with Backup Exec 9.1 for Windows Servers, the Backup Exec 9.0 Remote Agent is also compatible. The Backup Exec 8.x Remote Agent for Windows NT is not compatible."
So while you upgrade from existing Backup Exec v8.6 to 9.1, kindly Update all agents/options on all remote systems because the remote agent software component which gets installed on the remote system is different for both the versions of Backup Exec V8.6 and v9.1.
Upgrading from 8.x to 9.1 includes upgradation of the remote agents as well. You can upgrade the Remote Agents on top of the existing version. Or you can perform a fresh install i.e. uninstall and re-install the Remote Agent for Windows Server. Refer to the following technote for the same:
