If you are already using Debian wheezy, you should be able to add 
backports and just update, though you may have to make some mods in 
smb.conf to account for any slight changes since 3.6.

You do not have to upgrade to AD unless you want to, but it might make 
sense to set up a test domain and see if a Samba4 AD domain is better 
for you.
