Thank you @John Paul and @Tej_Singh_Rana
I went into the theory and demo again .Also did the practice lab associated with it where i upgraded the cluster from 19 to 20.
But I got the question from above in tthis scenario :
I went to katakoda kubernetes cluster with 18 version. Then my target is to upgrade it to 20 finally.
Step 1 : I upgraded it to 19 using the steps in kubernetes document. Everything is fine and master is 19 version.
Step 2 : I tried to upgrade kubeadm to 1.20.0 . I got stuck here . Please find the screenshot below
