Subject Re: How to change stateFomat to 2
Date Tue, 18 Apr 2017 17:21:07 GMT
Thanks Erick!
state.json exists for each collection in the "tree" view of admin UI. So,
that format is set to 2. I will call the CLUSTERPROP collections API too
and set legacyCloud=false whenever I create a collection.

Thanks
