FreeBSD has a tool for binary upgrades now, and has had a process for source based upgrades forever. This is all documented in the FreeBSD Handbook, and I'd be surprised if the source based upgrade wasn't in there since the beginning of the Handbook, which I think came out with FreeBSD-3.

But, darkhelmet and I were discussing updating FreeBSD at Yahoo; doing the update from the Handbook wouldn't be the right way to do it, because you would miss out on Yahoo specific patches, which were likely required for some key Yahoo software. I don't think it was common knowledge how to do it, so some documentation might have been nice, but mostly teams at Yahoo just didn't do it at that time for better or worse.

The tooling at Y! sounded quite good from the descriptions. Kind of confirmed my thoughts that the proper way to run a FreeBSD system is to make hopping versions not affect hosted applications through specific tooling and/or infrastructure. Especially the bit about building on older versions and such. Not really sure what more would address the version complaints from @rsync.
