The easiest way to migrate is to set up a new computer, install the
version of Samba that you want to use, join this to the domain as a new
DC. When you are sure that replication etc is working correctly,
demote and remove the old DC.

Trying to change from one set of packages to another will always have
a slight chance of a mistake creeping, it very probably won't happen,
but it might.
