Minor version upgrade of Istio from 1.5.1 to 1.5.10

How do i upgrade Istio from 1.5.1 to 1.5.10. I have used istioctl manifest apply --set profile=demo --set values.kiali.contextPath=/istio/kiali to install 1.5.1 version. I generated the manifest using istioctl manifest generate --set profile=demo > demo.yaml. Now when i try to upgrade to 1.5.10 I see default profile is not getting applied. I see istiod,ingress and prometheus and it looks like its picking default profile!

Steps i followed
istioctl manifest generate --set profile=demo > demo.yaml
downloaded istio 1.5.10 and copied to the path
istioctl upgrade -f demo.yaml --set values.kiali.contextPath=/istio/kiali
