Having issue to upgrade akv2k8s in AKS version 1.20.x

[itsabhipaul]

We had some issue with node restarts and pods are not moving to other nodes and that causing an outage. Microsoft requested to upgrade the AKS cluster from 1.18 to 1.20.x
After the upgrade we are getting error " Error: configmap "akv2k8s-ca" not found "
And its a known issue as per "#147"
Installed version is azure-keyvault-env:1.1.0 .
All the pods for azure-key-vault-controller and injectors are running under namespace " extensions "
So I tried to upgrade the "akv2k8s" but its not working. all 3 application pods are down.
I was checking this URL to upgrade akv2k8s " https://akv2k8s.io/installation/upgrade/ "
The commands i have used is ,
#helm upgrade --install akv2k8s-ca spv-charts/akv2k8s --namespace extensions
Release "akv2k8s-ca" does not exist. Installing it now.
Error: rendered manifests contain a resource that already exists. Unable to continue with install: ClusterRole "akv2k8s-ca-controller" in namespace "" exists and
cannot be imported into the current release: invalid ownership metadata; annotation validation error: key "meta.helm.sh/release-namespace" must equal "extensions":
current value is "com-att-igemsng-azure-dev"

All 3 application pods are running under namespace "com-att-igemsng-azure-dev"

Should I need to uninstall /remove the existing version and install new ? if so It would be nice if anyone can share the information about the removal and re-installation ?!!!
Before we remove the old version should i need to take any details ?
