Upgrade MongoDB Version and FCV¶

On this page

Overview
Procedure

You can upgrade the major, minor, or feature compatibility versions of your MongoDB resource. These settings are configured in your resource’s CustomResourceDefinition.

Overview¶

To upgrade your resource’s major or minor versions, set the spec.version setting to the desired MongoDB version.

To modify your resource’s feature compatibility version, set the spec.featureCompatibilityVersion setting to the desired version.

Note

If you update spec.version to a later version, consider setting spec.featureCompatibilityVersion to the current working MongoDB version to give yourself the option to downgrade if necessary.

To learn more about feature compatibility, see setFeatureCompatibilityVersion in the MongoDB Server Documentation.

Procedure¶

To upgrade the standalone deployment’s MongoDB version to 4.2.2-ent, complete the following steps:

1

Change the resource’s CustomResourceDefinition as shown in the following example:¶

Set spec.version to the desired MongoDB version.
Set spec.featureCompatibilityVersion to the current working MongoDB version:

copy

---
apiVersion: mongodb.com/v1
kind: MongoDB
metadata:
 name: my-standalone-downgrade
spec:
 version: "4.2.2-ent"
 type: Standalone
 project: my-project
 credentials: my-credentials
 persistent: false
...

The following example shows the result of this change:

copy

spec:
  version: "4.4.18-ent"
  featureCompatibilityVersion: "4.2"

2

Reapply the configuration to Kubernetes.¶

copy

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.
