Should not be a problem to license and active the 2019 VMs in this manner. The 2019 instances will need 2019 user or device Cals though.

We have an existing 2016 Standard Server with two 2016 VMs. We want to stack two 2019 VMs using a 2019 Standard Server License. Do the original 2016 CALs cover this or are 2019 CALs needed to be purchased also?
