Change a collection's storage-gateway?

[Ken Carlile]

Hi folks, 

Is it possible to change which storage-gateway a collection is attached to? 

I have a couple of long standing managed collections that I've recently changed the underlying storage for. The new storage has QoS limits set on it, which appears to be causing timeout errors and checksum verification errors on transfers. My guess is these errors are caused by the latency introduced by the QoS rules (which is intentional). 

I'd like to reduce the concurrency/parallelism on those collections, but not on my other collections under the same storage-gateways. 

Thanks, 

Ken
