FreeBSD/alpha 4.11-STABLE Release Notes | ||
---|---|---|
Prev |
If you're upgrading from a previous release of FreeBSD, you generally will have three options:
Using the binary upgrade option of sysinstall(8). This option is perhaps the quickest, although it presumes that your installation of FreeBSD uses no special compilation options.
Performing a complete reinstall of FreeBSD. Technically, this is not an upgrading method, and in any case is usually less convenient than a binary upgrade, in that it requires you to manually backup and restore the contents of /etc. However, it may be useful in cases where you want (or need) to change the partitioning of your disks.
From source code in /usr/src. This route is more flexible, but requires more disk space, time, and technical expertise. More information can be found in the ``Using make world'' section of the FreeBSD Handbook. Upgrading from very old versions of FreeBSD may be problematic; in cases like this, it is usually more effective to perform a binary upgrade or a complete reinstall.
Please read the INSTALL.TXT file for more information, preferably before beginning an upgrade. If you are upgrading from source, please be sure to read /usr/src/UPDATING as well.
Finally, if you want to use one of various means to track the -STABLE or -CURRENT branches of FreeBSD, please be sure to consult the ``-CURRENT vs. -STABLE'' section of the FreeBSD Handbook.
Important: Upgrading FreeBSD should, of course, only be attempted after backing up all data and configuration files.
