Can single k8 cluster have 1.4 and 1.5 versions installed?

we want to test 1.5 without 1.4 upgrade so is it possible to install 1.4 and 1.5 both versions in same cluster at a same time (may be in different namespaces)?

AFAIK its not possible because the CRD objects but want to check with community.

Hi @deepak_deore

i find this may be this help you

I mentioned 1.4 in the subject.

as per the doc you gave says:
Istio 1.6 will support a new upgrade model to safely canary-deploy new versions of Istio

Sorry. Dont know about it.
