EOL for support on RHEL 7.0 through 7.3
Veritas plans to end-of-life (EOL) NetBackup master servers, media servers, and clients running on Red Hat Enterprise Linux (RHEL) 7.0 through 7.3. These operating systems will no longer be supported platforms and the last release supporting these will be the NetBackup 9.1 release.
You will need to migrate to a supported version of RHEL before attempting to upgrade to later than the NetBackup 9.1 release. RHEL 7.0 through 7.3 master server, media server, and client will continue to be supported on older versions of NetBackup and follow the published Veritas Product End of Life policy guidelines.
