Another db - another connection. But Robomongo works only with one connection in one period of time. That is why it is impossible.

I suggest you to use mongoimport/mongoexoprt tools for your task. They comes with mongo, are located in same folder as mongod.exe and allows to move collections via databases, by exporting to and importing from a json file.

Code sample:

mongoexport --db testFrom --port portFrom --username userFrom --password passwordFrom --collection yourCollection --out test.json
mongoimport --db testTo --port portTo --username userTo --password passwordTo --collection yourCollection --file test.json
