Hi,
-Performing an upgrade from Backup Exec 9.0 for Windows Servers to version 9.1 requires an upgrade of the media server and all remote agent and Options on remote computers.
After the upgrade of these components, a reboot of both the media server and the remote servers are required. It is not necessary to uninstall any Backup Exec components prior to performing the upgrade.
-While it is possible to perform some basic level backups between a 9.1 media server and a 9.0 remote agent, some options will not work in this configuration, therefore leaving mismatched agent versions is neither recommended nor supported.
- Refer this technote:

- You can download and installv9.1 using the following technotes:

# BEWS 9.1 is a free downloadable upgrade inclusive of previously installed agents and options from Backup Exec 9.0 for Windows Servers agents and options.
