Starting in MongoDB 8.3, you can downgrade your MongoDB version to the immediately previous minor or major version.
Important
MongoDB 8.3 is the latest minor release. Starting with MongoDB 8.2, minor releases are available for on-premises deployments (Community and EA) for specific use cases. For more information, see MongoDB Versioning.
To install the latest MongoDB version supported for on-premises use, see the installation instructions.
Downgrade Path
If you need to downgrade from 8.3, downgrade to the latest patch release of 8.2.
MongoDB supports single-version downgrades along adjacent versions only. You cannot downgrade to a release that is multiple versions behind your current release.
For any MongoDB release, you can upgrade or downgrade to the immediately previous major or minor version.
Feature Compatibility Version and Downgrade
Starting with MongoDB 8.3, the setFeatureCompatibilityVersion supports downgrading the FCV to the previous minor version.
Follow the FCV downgrade steps in each procedure to ensure your deployment runs with a feature compatibility version that is supported by the target MongoDB version.
