Traefik v1.7.x to Traefik v2.x.x ingress controller migration

Traefik Traefik v2
1

Hello everyone, I need some advice. Currently my k8s cluster using traefik v1.7.x for the ingress rule. I use helm to install the traefik. I also apply some ingress yaml that look like this:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  namespace: myapp
  name: demo.mydomain.com
  annotations:
    kubernetes.io/ingress.class: traefik
    ingress.kubernetes.io/custom-response-headers: 'X-Powered-By:Love||X-Server:Love||Server:Love||Cache-Control:max-age=2592000,public'
    ingress.kubernetes.io/browser-xss-filter: 'true'
    ingress.kubernetes.io/content-type-nosniff: 'true'
    traefik.ingress.kubernetes.io/redirect-entry-point: https
    traefik.ingress.kubernetes.io/redirect-permanent: "true"
    ingress.kubernetes.io/frame-deny: "true"
    ingress.kubernetes.io/custom-frame-options-value: "SAMEORIGIN"
    ingress.kubernetes.io/content-security-policy: upgrade-insecure-requests
    #traefik.ingress.kubernetes.io/affinity: "true"
    traefik.ingress.kubernetes.io/buffering: |-
      maxrequestbodybytes: 10485760
      memrequestbodybytes: 10485760
      maxresponsebodybytes: 10485761
      memresponsebodybytes: 10485760
      retryexpression: IsNetworkError() && Attempts() <= 2
    traefik.ingress.kubernetes.io/rate-limit: |
      extractorfunc: client.ip
      rateset:
        wlc:
          period: 1s
          average: 50
          burst: 100
spec:
  rules:
  - host: demo.mydomain.com
    http:
      paths:
      - path: /
        backend:
          serviceName: myapache
          servicePort: 80

Now, I want to upgrade to traefik v2.x.x for future proof. How to upgrade with less hassle? Or any step by step that I can read?

Thank you very much

Start with the migration guide: https://docs.traefik.io/migration/v1-to-v2/

There are a few other blog posts as well, but I am not sure if it covers K8s. I made one, but it was for docker/docker-compose.
