You can follow the upgrade path:

To upgrade an existing MongoDB deployment to 4.0, you must be running a 3.6-series release.

To upgrade from a version earlier than the 3.6-series, you must successively upgrade major releases until you have upgraded to 3.6-series. For example, if you are running a 3.4-series, you must upgrade first to upgrade first to 3.6 before you can upgrade to 4.0.
