Moving collections to new rs


Currently I have mongo cluster with one RS,
I want to move couple of collections to a separate and new RS without performing downtime or reducing it to the minimum.

I have looked for couple of solutions but either of them gave me easy and clean transition,
can you recommend me how to do this kind of change?

@Kobe_W it creates a lot of moving parts to do this kind of copy,
and it is one of many I have to do…
