Well, I tried to switch by doing a "svn switch" in /usr/src, building a
kernel, restarting the kernel in single user mode and then trying to
build the world. At some point in /usr/src/share (I forgot were exactly,
it was somewhere with lots of locale stuff), the buildworld process
fails so I couldn't build a world.

/usr/src/UPDATING says this:


To upgrade in-place from 8.x-stable to current
----------------------------------------------
<make sure you have good level 0 dumps>
make buildworld [9]
make kernel KERNCONF=YOUR_KERNEL_HERE [8]
[1]
<reboot in single user> [3]
mergemaster -p [5]
make installworld
mergemaster -i [4]
make delete-old [6]
<reboot>


Even though it says 8.x, I would start from these instructions.

Cheers

Tom
