For the Junos upgrade you will have to follow the same steps as you did when you first installed the vMX. which effectively means no issu and no traditional request software add... etc. You are looking for a downtime for sure (extended or not depending on the engineer's skills)
Following are the getting started guides that has detailed steps on how to install a vMX. vMX Getting Started Guide for VMware : https://www.juniper.net/documentation/en_US/vmx18.3/information-products/pathway-pages/getting-started/vmx-gsg-vmware.pdf vMX Getting Started Guide for KVM : https://www.juniper.net/documentation/en_US/vmx18.3/information-products/pathway-pages/getting-started/getting-started.pdf With regards to the questions about performance Juniper will give you some guidelines but they are no binding in any sense this is a uncharted territory for all of us and everything depends on the use case and the traffic load. If something happens (you are on your own) no service contract will cover you Juniper will blame the hypervisor vendor and the other way round. Don't put anything into production if you don't test it thoroughly and don't trust anyone else but what you see in the lab. Also something else you need to know and observe is that the vswitch has no state which effectively means you need to enable bfd on your interfaces if you want to have some decent convergence.
