I used the binary upgrade procedure[1] (since I mostly use -RELEASE 
versions of FreeBSD), something like this:

# freebsd-update -r 10.1-RELEASE upgrade
# freebsd-update install
# reboot
# freebsd-update install
# pkg_list=$(pkg info -aoq)
# pkg delete -a
# pkg install $pkg_list
# freebsd-update install

HTH,
Greg.

PS: Sorry for the slow response - I'm just back from summer holidays.

PPS: In reality I like to maintain a separate list of installed 
top-level packages for $pkg_list so that the dependencies are installed 
automatically and marked as automatic when I look at:
# pkg query "%a %n"
