Test Migrate v1beta1 To v1beta2

https://github.com/longhorn/longhorn/issues/10250

Test Steps

Given A single-server K3s cluster

Ref: https://docs.k3s.io/architecture?_highlight=single&_highlight=server#single-server-setup-with-an-embedded-db Example: https://github.com/k3s-io/vagrant-k3s

And Install necessary command line tools on master node

sudo zypper in jq sqlite3
sudo snap install kubectl --classic

And Longhorn v1.2.x installed

And Create a RWX volume

kubectl apply -f - <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: longhorn-share
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5Mi
  storageClassName: longhorn
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-world
  labels:
    app: hello-world
spec:
  replicas: 1
  selector:
    matchLabels:
      app: hello-world
  template:
    metadata:
      labels:
        app: hello-world
    spec:
      containers:
        - name: hello-world
          image: busybox
          command: ['sh', '-c', 'while true ; do now=$(date +%s) ; echo $now ; echo $now >>/mnt/data/share/log || echo $now >/mnt/data/share/log ; ls -l /mnt/data/share/log ; sleep 1 ; done']
          volumeMounts:
            - mountPath: /mnt/data/share
              name: share
      volumes:
        - name: share
          persistentVolumeClaim:
            claimName: longhorn-share
EOF

And Create a backup target

Ref: https://longhorn.io/docs/1.9.0/snapshots-and-backups/backup-and-restore/set-backup-target/

And Create a recurring job to backup the volume

Ref: https://longhorn.io/docs/1.9.0/snapshots-and-backups/scheduling-backups-and-snapshots/

And Create a backing image from the volume

Ref: https://longhorn.io/docs/1.9.0/advanced-resources/backing-image/backing-image/#create-a-v1-backing-image-using-yaml

When Upgrade Longhorn to v1.9.x through valid upgrade path

1.2.x -> 1.3.x -> 1.4.x -> 1.5.x -> 1.6.x -> 1.7.x -> 1.8.x -> 1.9.x (master) Ref: https://longhorn.io/docs/1.9.0/deploy/upgrade/

And Wait until Longhorn components are running

Then Log in to K3s master node with root permission
