So depending on your version of samba you'll have to update just the 
binaries or also to update the structure and the content of the database.

Best is to first know the version.

Upgrading the binaries is ok there is nothing to do apart from make;make 
install , to update the structure we have a tool but for the moment it's 
limited to 1 DC (so you have to demote your other server). In theory we 
could support multi DC upgrade, but I have a bit of work to do but it 
shouldn't be too hard.
