Change the Version of MongoDB

On this page

  • Considerations
  • Prerequisites
  • Procedure

You can upgrade or downgrade MongoDB versions within the same Feature Compatibility Version (FCV) in Ops Manager sharded clusters, replica sets, and standalone MongoDB instances while maximizing the availability of your deployments.

You can add custom-built versions of MongoDB for Ops Manager to download.

If Ops Manager doesn't manage your deployment, change the version of MongoDB manually. To learn more, see upgrade tutorials for each MongoDB release.

Note

Ops Manager support for End of Life MongoDB versions

Ops Manager doesn't support Backup, Monitoring, or Automation for versions earlier than MongoDB 3.6.

Ops Manager continues to support Automation, Backup, and Monitoring using the MongoDB Agent for clusters running MongoDB 3.6 or later.

  • Check the following documents for any considerations or compatibility issues before changing a deployment's MongoDB version:

  • Plan the version change during a predefined maintenance window.

  • Change the MongoDB version on a staging environment before changing a production environment. Your staging environment should mirror your production environment. This can help avoid compatibility issues that may result in downtime for your production deployment.

  • Follow the MongoDB release notes when performing manual upgrades of replica sets and sharded clusters.

Note

Downgrading Limitations

You cannot downgrade a MongoDB deployment:

  • From version 5.0 to any version before 4.4.0

  • From version 4.4 to any version before 4.2.6

  • From version 4.2 to any version 4.0.12 (for Windows) or 4.0.7 (for Linux)

  • From version 4.0 to any version before 3.6.23

If the MongoDB deployment has its Feature Compatibility Version set to the same release series as its Version, you must first manually downgrade the instance's featureCompatibilityVersion.

Note

If you're running in local mode and don't see your desired version, you can Update the Version Manifest Manually.

To learn more, see Local Mode Configuration.

For each MongoDB process that you want to change:

  1. Click the current version number for the process.

  2. Click the desired version number.

If you are upgrading to a new major version, and wish to enable features offered in the new major version, you must also update the featureCompatibilityVersion.

For each MongoDB deployment that you want to change:

  1. Click the current featureCompatibilityVersion for the deployment.

  2. Click the value that matches the desired version number.
