FreeBSD Upgrade Procedures

Posted By Ralf S. Engelschall On Friday, July 13, 2007 @ 16:49 In Hacking | No Comments

Since many years I investigate on out-of-the-box FreeBSD upgrade procedures [1] which especially allow one to upgrade a FreeBSD server fully remotely via an SSH connection and without console access or even single-user requirements.

The ultimative killer procedure here certainly was the FreeBSD 4.x to 5.x upgrade procedure [2] which used a hard-core in-place system overwriting approach in order to avoid the usual requirement for console access and single-user mode. Hence it was suitable for upgrading a server in a Datacenter remotely via just SSH access. It was successfully used to upgrade many dozen FreeBSD servers in production environments.

The recently developed and used FreeBSD 5.x to 6.x upgrade procedure [3] again was a more simple one. This is the procedure which is currently in use when moving to the latest FreeBSD-STABLE. It also was used upgrading about two dozen FreeBSD servers in Datacenter environments.

As FreeBSD 7-CURRENT fast approaches the RELENG_7 (aka 7-STABLE) branch now, I thought it is time to finally provide a FreeBSD 6.x to 7.x upgrade procedure [5] now, too. It is still not tested as well as the other procedures. But this will be changed on-demand over the next months, of course.

In case you want to just try out FreeBSD 7, please directly install FreeBSD 7 via one of the snapshot ISO images [6]. But if you want to upgrade an existing system, then this new upgrade procedure might safe you some hassles. Hope it helps you, too.
