I've heard from a post somewhere that a migration Secondary-Primary can be 
done. Our best way to do this will be to put de VM on pause. Put the drbd disk 
on Secondary. Then migrate the vm to the second host, then put the drbd disk on 
second host to primary and unpause the vm. I've searched on google and I can't 
find anything on this method.

Is there a way to do this? Is there another way you are thinking of?

What about a drbd device per vm, both set active/active? Migration already ensures that only one vm at a time can write to the underlying device through its pause/unpause mechanics.
