remote server running 3.0.0
local server running 3.2.1

When I try to copy from remote to local I see the skeleton of the database (collections etc) but not the contents.

Using mongoDump I look at files created and looks like there is data there, however mongo 3.2.1 is unable to parse that data.
This maybe a versioning, relatively new on mongodb so excuse my ignorance.
If I am doing something wrong please state.
Windows 10 (both machines)

Is this a case of just running same version for workaround?
