Downgrading the VTS server
Complete the following steps if you want to downgrade the server (to a previously installed
version of 6.04). The following occurs when you downgrade the server:
• Backup of /usr/local/tape/ is restored
• System restore image is restored
• VTS server is downgraded
Note Operating system RPMs that were installed during an upgrade are not reverted. If
desired, you must manually uninstall these RPMs. Also, it is recommended that you
downgrade all servers in your VTS environment.
