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.
This page lists procedures used to downgrade from 8.3 to 8.0.
Downgrade Path
If you need to downgrade from 8.3, downgrade to the latest patch release of 8.0.
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 versions, major or minor, you can upgrade or downgrade to its adjacent neighbors. For example, you can downgrade from 8.3 to 8.2 or upgrade from 7.0 to 8.0.
For all versions, major or minor, you can downgrade to the immediately previous major version. For example, from 8.3 to 8.0.
For any minor version, you can upgrade to the immediately next version. For example, from 8.2 to 8.3.
Feature Compatibility Version and Downgrade
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.
