Upgrade on Kubernetes using the MSR Operator

To upgrade from MSR 3.0.x to 3.1.x, use the Mirantis Migration Tool (MMT).

To upgrade to a new patch version:

1. Edit the custom resource manifest to include the MSR version to which you plan to upgrade:

   spec:
     image:
       tag: <3.1.x>
   

2. Apply the changes to the custom resource:

   kubectl apply -f cr-sample-manifest.yaml
   

3. Verify completion of the reconciliation process for the custom resource:

   kubectl get msrs.msr.mirantis.com
   kubectl get rethinkdbs.rethinkdb.com
