Read this and the following sections on upgrading your
system thoroughly before beginning an upgrade installation.
They describe:
the different types of installation you can choose if you
are already running an SCO operating system
steps you must take before or after installing the new
system so that certain components from your previous
system continue to work as you expect
Also read the chapters in the Release Notes that discuss the installation.
CAUTION:
Before beginning any installation or upgrade, make sure you
have up-to-date backups of all the data currently on
your system (see the System Administrator's Guide).
Some of the options available during installation
overwrite all the data on the hard disk, including
user data and DOS partitions.
We recommend that you use
cpio(C)
format for the backups (the Backup Manager
uses cpio), and that you back up one filesystem
per tape.
If you currently run an earlier version of an SCO UNIX
operating system, one or more of the following methods are
available for you to upgrade to an SCO OpenServer system.
Read the referenced sections and the Release Notes to decide
which method works best for your system.
Choose a Fresh installation, then choose the
Preserve option
for setting up your hard disk.
Choose a Fresh installation, then run
Interactive fdisk/divvy
to recreate your current hard disk setup.
Choose a Fresh installation, choose the
Use whole disk for UNIX or
Customize option
for setting up your hard disk, then restore the data from backups.
NOTE:
If your system is currently running SCO Internet FastStart
release 1.0 or 1.1, you must select the Fresh installation type.
You may select either the
Interactive fdisk/divvy
or
Preserve
option for setting up your hard disk.
You cannot select the Upgrade installation type for
SCO Internet FastStart release 1.0 or 1.1.
Before reinstalling your system, read the
Release Notes for instructions on how to migrate your current Internet FastStart
data. This information will help you save sendmail,
ppp, and server configuration information so that
you do not need to completely reconfigure these services.
