Upgrading from an SCO Open Desktop system

To preserve the hard disk setup of an SCO Open Desktop Release 3.0 or 2.0, select Fresh as the Installation type, then select Preserve under Hard disk setup. (See ``Choosing an upgrade path'' in Chapter 2 of the SCO OpenServer Handbook.) You must start the installation on an active UNIX partition with a clean root filesystem with device nodes that match those in /etc/default/filesys. Your current SCO system must be on the first division of the active partition.

• Back up your current system and verify that the backup was successful. See ``Running unscheduled filesystem backups'' in the System Administration Guide.

• Run fsck(ADM) with the -ofull option, and shut the system down cleanly.
