HSM on S3 and mailbox move

[Klug]

Hi everyone.

Let's say I've a multi-store setup.
Each store has its secondary HSM volume on S3.

The question: if I mailbox move an account from one server to another one, will all the data in the HSM be moved too?
In other words, does it works like a "standard" (non S3) HSM volume (and data has to be move between servers AND volumes)?

Got an answer.

The server ID is hardcoded in the path.
So even if you share a single bucket between servers, when you move an account from one server to the other, all the mails will be moved too...

Is that (shared bucket) the new "Centralized" feature of HSM-NG?

ChangeLog is the only pointer available and it says: "Added ability to create 'Centralized' stores (BETA): MailboxMove operation is significantly faster when using centralized storage, as blobs stored on a centralized store stay there, with only metadata and references being copied."
