Splunk has custom mongod builds as well as mongodump/mongorestore.

They're asking what specific mongodump / mongorestore versions to support mongod 4.4, 5.0, 6.0.

It would be nice to have the commands that show the version names as well.

"Currently we're using custom mongodump and mongorestore. Do you know if they support all MongoDB 4.4, 5.0, and 6.0?

Are our custom mongodump and mongorestore built off of a version that supports all Mongodb 4.4, 5.0, and 6.0?"
