HP-UX and AIX support change

NetBackup 8.1.2 does not support the upgrade of an HP-UX or an AIX master or media server. Before upgrading to NetBackup 8.1.2, you must migrate your exiting HP-UX or AIX master or media server to a supported NetBackup platform. Refer to the NetBackup Master Compatibility List for information on supported platforms.

Veritas developed the NbServerMigrator tool to help you migrate your NetBackup master server. NbServerMigrator migrates your source master server to a target master server running on the same NetBackup version. More information about the NetBackup Master Server Migration Guide 1.0 is available.
