On this page

  • Prerequisites
  • Procedure
  • In your , the settings as shown in the following example:
  • Reapply the configuration to Kubernetes.

Update the major and minor versions of your Ops Manager instance and backing databases in the Ops Manager Resource Specification that the Kubernetes Operator uses to manage your deployment.


To maintain existing settings and availability, back up the following in your current Ops Manager instance:

  • Your to a secure location. The stores settings for the Ops Manager instance.

  • Your gen.key files to a secure location. The gen.key provides details to encrypt and decrypt Ops Manager's backing databases and user credentials. Ops Manager might delete these files as part of the upgrade process.

As an extra precaution, you may use mongodump to create a binary export of the Application Database. No officially supported backup method exists for the Application Database. If the upgrade fails, reach out to MongoDB Support for help fixing the issue with the Ops Manager version.

  1. Upgrade Ops Manager by following the considerations, prerequisites, and procedure in Upgrade Ops Manager.

  2. Reference Use a Compatible MongoDB Version to ensure your backing databases use a MongoDB version that is compatible with the new Ops Manager version.

  3. If you need to upgrade your backing databases to a compatible MongoDB version, see Upgrade MongoDB Version and FCV.

To upgrade Ops Manager and the application database versions, complete the following steps:

  1. Set spec.version to the new Ops Manager version.

  2. If you upgraded your application database, set spec.applicationDatabase.version to the compatible MongoDB version.

  1. (Optional) If you might need to downgrade, set spec.featureCompatibilityVersion.
