Change the Version of MongoDB

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 does not manage your deployment, you need to change the version of MongoDB manually. To learn more, see upgrade tutorials for each MongoDB release.

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.

Downgrading Limitations

You cannot downgrade a MongoDB deployment:

  • From version 3.6 to any version before 3.4.0
  • From version 3.4 to any version before 3.2.8


Remove Incompatible MongoDB Features when Downgrading

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



On the line listing the deployment item, click Modify.


Verify the desired version number is in the version list.

In the Cluster Configuration section, the Cluster Settings heading lists the processes with their names, MongoDB versions, data directories and log files.

  1. Scroll to the Cluster Settings heading.
  2. Click the Version arrow for the first MongoDB process in the list.


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.


Change the version of MongoDB for the deployment.

For each MongoDB process that you want to change:

  1. Click the current version number for the process.
  2. Click the desired version number.

(Optional) Update the featureCompatibilityVersion.

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.

Click Save.
