Choosing an upgrade path

Options for upgrading existing SCO OpenServer systems

If you currently run an earlier version of an SCO OpenServer operating system, you can use one or more of the following options to upgrade to an SCO OpenServer Release 5.0.7 system:

the Upgrade installation
a Fresh installation, using the Preserve option for setting up your hard disk
a Fresh installation, running Interactive fdisk/divvy to recreate your current hard disk setup
a Fresh installation, selecting the Use whole disk for UNIX or the Customize option for setting up your hard disk, then restoring your current data from backups

CAUTION: Before you begin any of these upgrade installations:

Back up all of the data currently on your system and verify that the backup is successful. Some of the upgrade options will overwrite all the data on the hard disk, including user data and DOS partitions.
We recommend that you use cpio(C) format (used by the Backup Manager) for your backups. See ``Running unscheduled filesystem backups'' for more information.
Run fsck(ADM) with the -ofull option, and shut the system down cleanly.
