Downgrading VTS
Complete the following steps if you want to downgrade VTS (to 8.0). The following is
performed by the downgrade process:
• Backup of /usr/local/tape/ is restored
• System restore image is restored
• VTS is downgraded
• System restore image is deleted
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 appliances in your VTS environment.

appliance before downgrading.
