how do I transfer ownership of a VM to another account

[Holdingdigital n]

I want to transfer some VM's from one azure account to another, the documentation is not clear on how to do it or if its even possible.

I have to transfer the VM's  form one company account to another company account hopefuly without interrupting the services they are enabling for long,  like company1@outlook.com has ownership of the VM and I want to give it to company2@outlook.com so that the billing, administration and everything related is transfered to company2.

please help

Hi 

Do you want to give admin access only for that VM or for the entire subscription ?

No, I only want to transfer ownership of the VM, so that the company that is giving me the VM wont have access anymore, and I get all permisions to use it configure it etc.

Unless I am missunderstanding the way subscriptions work, if they can transfer the subscription to my company account, including the VM's I need, and they keep their account with whatever other subscriptions they have; then I guess the subscription transer could work.
