Hi,
We recently upgraded our server from 2.6.11 -> 3.0.8 -> 3.2.10.
Once this upgrade was completed we want to upgrade engine of config server. So we followed the steps here - https://docs.mongodb.com/v3.2/tutorial/change-config-server-wiredtiger/.
However once we changed engine to wired tiger the mongorestore is not working
