Upgrade Path
Important
Before you upgrade or downgrade a cluster, ensure all cluster members are running. If you do not, the upgrade or downgrade will not complete until all members are started.
For any MongoDB release, you can upgrade or downgrade to the immediately previous major or minor version.
