3 Upgrading from previous releases of FreeBSD

Source upgrades to FreeBSD 6.4-STABLE are only supported from FreeBSD 5.3-RELEASE or later. Users of older systems wanting to upgrade 6.4-STABLE will need to update to FreeBSD 5.3 or newer first, then to FreeBSD 6.4-STABLE.

Important: Upgrading FreeBSD should, of course, only be attempted after backing up all data and configuration files.

This file, and other release-related documents, can be downloaded from http://www.FreeBSD.org/snapshots/.
