Hi Indra, The Json deserialization error is an expected one, after you upgrade. It ll keep coming until the new systemvms come up using the new systemvvm template. All the steps you have executed are correct and you don't need to change those.
As soon as you upgrade and start management server, you will see Json deserialization error, that is expected. After that when you run the cloudstack-sysvmadm command the new systemvms using the new templates will come up and you won't see that error anymore. Are they not coming up even after running cloudstack-sysvmadm command?? Can you copy the full management server log somewhere so that I can have a look?

I did use the wrong filename when registering the template (systemvm-kvm-4.2.0 instead of systemvm-kvm-4.2) due to wrong information given by Abhinav but I have since corrected it prior to the upgrade, by renaming the template name (rather than deleting the template and re-register it). My questions: 1. Do I need to get the template name right when I register the systemvm-kvm-4.2 template from the beginning, prior to the upgrade? 2. Do I need to delete the old system VM template from the template list, prior to the upgrade? If yes, I think this should be inside the documentation. Looking forward to your reply, thank you. Cheers.
