About master server upgrades
Upgrade NetBackup on the master server before you upgrade NetBackup on any other computers in your environment. Once the master server upgrade is finished, you can upgrade media servers, and then clients. NetBackup supports a mixed version environment. More information about this topic is available.
See About compatibility between NetBackup versions.
Note:
Remember to update NetBackup OpsCenter before you update your NetBackup master servers. You must also disable OpsCenter data collection. See the NetBackup OpsCenter Administrator's Guide for complete information.
NetBackup includes an administration console for all the supported versions of NetBackup. More information about supported versions of NetBackup is available.
Note:
Veritas recommends that after you install or upgrade NetBackup server software, you should uninstall older versions of the Remote Administration Console (Windows and Java) present on the host. If the native NetBackup Administration Console for Windows is present, it is automatically uninstalled when you install or upgrade the NetBackup server software.

Proceed with the upgrade.
