[Samba] Migrate DC from Small Business Server 2011 to Samba 4

[L.P.H. van Belle]

Hai, 

Your first option should be fine BUT.. I suggest setup new, why?
No leftovers from older setup, so less problems.
And that .local domain is gone then then your able to setup better. 

Gives the advantage to keep the old server as is and use domain trust. 
That give you more time and room to setup new. 

Just my idea.. 

Greetz, 

Louis
