Could you please advise on how to move from my existing DS218+ (2 x 4TB) to a brand new DS920+? The 218+ is running DSM 7, which I assume the 920+ won't be. Is it possible to upgrade the DS920+ to DSM 7 and then swap the drives from the DS218+ into slots 1&2? I assume that the DS920+ needs at least one blank drive in bay 1 to allow the DSM 7 update. Once I do that, can I eject it and use it elsewhere instead? I have ordered 2 x 2TB drives for the DS218+, as we plan to keep it as a remote backup for the new DS920+.
No answers for that question.
