MongoDB 8.3 Release Candidates
MongoDB 8.3 binaries are currently available only as release candidates. Release candidates can be used for early testing of new features, but are not suitable for production deployments.
This version of the manual is for an upcoming release and is currently a work in progress.
This page lists procedures used to downgrade from 8.3 to 8.2.
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 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
Starting with MongoDB 8.3, the setFeatureCompatibilityVersion
supports downgrading the FCV from 8.3 to 8.2.
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.
