Updating NetWorker from 7.6.x
When updating the NetWorker software from 7.6.x, some Linux operating systems and the
Windows operating system allows you to update the NetWorker software without removing
the previous version. For HP-UX, AIX, Debian, and Ubuntu you must remove the previous
version of the NetWorker software, then install the newer version.
