My experiences converting a couple of systems from 9-STABLE to 10-STABLE 
over the last couple of months were really pretty easy.  These were 
source updates for both base and ports.  Despite changing from pkg_* to 
pkg and KMS X drivers at the same time, it was surprisingly smooth.

If you have devel/ccache installed, remove it before starting, though, 
it has problems with clang.  Using -DNOCLEAN with an existing /usr/obj 
can go even faster than ccache: less than two minutes for a buildworld 
on my frequently updated i5/SSD system, sometimes less than one minute.
