Deploy a proxy agent and worker in a different domain

Hi guys,

I have two domains one is my "production" and the other one my "test". In my production domain i have install the vra with two appliances two IAAS componets servers. In my production enviroment every works perfekt. Now I want to deploy a proxy agent and a worker in my test and connect it to my vra 7, is this possible without a trust of the domains? Does someone have a best practise guide for this or is it unsupported?

My enviroment:

Production:

-vCenter 6.0

-ESXi 5.5

-vra 7.0.1

Test:

vCenter 5.5

-ESXi 5.5
