This article is from a FAQ concerning SCO operating
systems. While some of the information may be applicable to any OS,
or any Unix or Linux OS, it may be specific to SCO Xenix, Open
This is an old article about SCO Unix and is only left here for historical purposes.

this site: Search this site is the best

If you are using OSR5, you simply install the new license pack
from SCOAdmin License.
If you are upgrading the user licence but staying on the same
release of the operating system, you need to rebrand the
appropriate files with the new serial number/activation key that
you get in the upgrade kit.
If you're upgrading to a more recent release, use the
intelligent upgrade procedure built into the upgrade package. This
will not only update your OS to the current level, but will also
upgrade your user licence to what you ordered.
