so I am about to migrate a single-drive pool (striped, encrypted) on my FN server to a bigger new drive (again single drive pool, striped encrypted). To avoid a rather slow copy process via SMB across another computer from the old dataset to the new, I thought about using a one-time replication task that copies all the data over to the new drive within FN not requiring an external machine and an SMB bottle-neck.
So the question I have is: Once done can I simply remove the old drive from the NAS and use the new pool with the replicated data as the new “original” and retire the old drive? Or is the replicated set somehow in some other fornat that makes it a “replicant” that can only be used to replicate it back to a fresh drive?
And: Is this the fastest way to do it or is it a bad idea? As I understand replication works on block level, so will the clone have the same encryption keys as the original or do I setup the new drive normally as an excrypted pool and the data will be cloned into that new pool with the new encryption?
(yes, it’s a single drive with a single dataset)
(Hope this made sense).
