I see this mentioned on the list about creating a new DC and migrating 
everything over vs. an in place upgrade. I would expect this practice to 
be detrimental to the rid pool. I would expect Samba to behave the same 
as a Microsoft DC. Once you demote and remove a DC, it's rid's are lost 
and can never be allocated.  This may be trivial with small networks, 
but with larger ones greater care has to be considered when choosing an 
in place vs. migration I expect.

On a side note all my DC's starting with Samba 4.0 has been on Ubuntu 
and doing an in place upgrade without fail. I also maintained my use of 
Ubuntu because of LTS. I don't do unattended upgrades however.
