Upgrade With Disk Space Reallocation

The upgrade option in the Solaris 8 Interactive Installation Program provides the ability to reallocate disk space if the current file systems don't have enough space for the upgrade. By default, an auto-layout feature attempts to determine how to reallocate the disk space so an upgrade can succeed. If auto-layout can't determine how to reallocate disk space, you must specify the file systems that can be moved or changed and run auto-layout again.

If you're creating an upgrade profile and the current file systems don't contain enough space for the upgrade, you can use the backup_media and layout_constraint keywords to reallocate disk space. "Reallocating Disk Space for an Upgrade" contains an example that shows how to use the backup_media and layout_constraint keywords in a profile.
