Change the Version of MongoDB

Ops Manager supports safe automatic MongoDB version upgrades and downgrades of managed MongoDB deployments while maximizing the availability of your deployment. Ops Manager can upgrade and downgrade sharded clusters, replica sets, and standalone MongoDB instances.

Add a Custom MongoDB Build describes how to choose which versions of MongoDB are available to Ops Manager.

If Ops Manager does not manage your deployment, you need to change the version of MongoDB manually. The MongoDB Manual provides upgrade tutorials with each release.

MongoDB 3.6 reached its End of Life date on April 30, 2021

Ops Manager doesn’t support Automation for MongoDB 2.6, 3.0, 3.2, 3.4, or 3.6.


  • 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.
