Mongodump will fail in newer versions like 100.7.3 when trying to dump from DocumentDB with an ”Unknown admin command atlasVersion” error. Conversely, mongodump 100.6.1 works on DocumentDB. The PR that introduces a command that documentDB can't support is the following: https://github.com/mongodb/mongo-tools/pull/500/files#diff-208faa39e11f6b639b4d9508135eed798fa055b83123dff99f4f0196121bc09eR132.

Since we don’t have any official way to migrate from DocumentDB would be nice to have mongodump work with it. However, mongodump does not officially work, and can result in data corruption is used with DocumentDB (aka use at your own peril).

Make mongodump work with databases like DocumentDB.
