Upgrade Ops Manager and Backing Database Versions¶

On this page

Prerequisites
Procedure

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

Prerequisites¶

Warning

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

Your conf-mms.properties to a secure location. The conf-mms.properties 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 Managers backing databases and user credentials. Ops Manager might delete these files as part of the upgrade process.
Your application database. If the upgrade fails, you need a current backup to restore your Ops Manager instance.

Upgrade Ops Manager by following the considerations, prerequisites, and procedure in Upgrade Ops Manager.
Reference Use a Compatible MongoDB Version to ensure your backing databases use a MongoDB version that is compatible with the new Ops Manager version.
If you need to upgrade your backing databases to a compatible MongoDB version, see Upgrade MongoDB Version and FCV.

Procedure¶

In your Ops Manager Resource Specification, set the following:

Set spec.version to the new Ops Manager version.
If you upgraded your application database, set spec.applicationDatabase.version to the compatible MongoDB version. Consider setting spec.featureCompatibilityVersion to give yourself the option to downgrade if necessary.

For example, the following resource updates Ops Manager from 4.0 to 5.0 and the application database to MongoDB 4.2.11-ent.

copy

apiVersion: mongodb.com/v1
kind: MongoDBOpsManager
metadata:
 name: om
spec:
 replicas: 1
 version: "5.0.0"
 adminCredentials: ops-manager-admin
 configuration:
  mms.fromEmailAddr: admin@example.com
  mms.security.allowCORS: "false"
 backup:
  enabled: true
  headDB:
   storage: "30Gi"
   labelSelector:
    matchLabels:
     app: my-app
  opLogStores:
   - name: oplog1
     mongodbResourceRef:
      name: my-oplog-db
     mongodbUserRef:
      name: my-oplog-user
  s3Stores:
   - name: s3store1
     mongodbResourceRef:
      name: my-s3-metadata-db
     mongodbUserRef:
      name: my-s3-store-user
     s3SecretRef:
       name: my-s3-credentials
     pathStyleAccessEnabled: true
     s3BucketEndpoint: s3.region.amazonaws.com
     s3BucketName: my-bucket

 applicationDatabase:
   passwordSecretKeyRef:
    name: om-db-user-secret
    key: password
   members: 3
   version: "4.2.11-ent"
   persistent: true
   podSpec:
     cpu: "0.25"

Reapply the configuration to Kubernetes:
copy
```
kubectl apply -f <om-resource-specification>.yaml
```
Kubernetes automatically reconfigures your deployment with the new specifications. You can see these changes reflected in your Ops Manager or Cloud Manager application.
