Upgrade MongoDB Version
On this page
You can upgrade the major or minor versions of your MongoDB resource. Configure these settings in your MongoDB Database Resource Specification.
Overview
To upgrade your resource's major or minor versions, set the
spec.version setting to the desired MongoDB version.
Note
If you update this value to a later version of MongoDB for your
database resources, the feature compatibility version remains
at the MongoDB version you're upgrading from to give you the option to downgrade if necessary.
If you want the feature compatibility version to match the new MongoDB version, you must manually set
spec.featureCompatibilityVersion to the new version or to AlwaysMatchVersion.
To learn more, see spec.featureCompatibilityVersion.
Procedure
To upgrade the standalone deployment's MongoDB version from 4.2.2-ent
to 4.4.18-ent, complete the steps in the following example.
Set spec.version to the desired MongoDB version.
apiVersion: mongodb.com/v1 kind: MongoDB metadata: name: my-standalone-downgrade spec: version: "4.4.18-ent" type: Standalone project: my-project credentials: my-credentials persistent: false ...
Reapply the configuration to Kubernetes.
kubectl apply -f <standalone-config>.yaml
Kubernetes automatically reconfigures your deployment with the new specifications. You can see these changes reflected in your Ops Manager or Cloud Manager application.
