Yes, you will have to transfer the FSMO roles to the new DC before 
demoting the old one, but you don't have to transfer them back, any DC 
can hold some or all the FSMO roles.

FSMO transfer is fairly stable on the later Samba versions (there was a 
recent minor glitch, but this has been fixed), so I would transfer them 
using samba-tool on the new Samba DC.

You shouldn't have a problem.
