[Observium] Using professional edition license for testing

Hello,

I want to migrate Observium professional edition to a new server, my plan is to install everything and testing them on the new box before moving data(rrd, database etc.).

I saw "The subscription license is valid for a single production installation and two testing or development installations." on the page so I want to make sure that how should I handle license operation. I only can see one user/pass for my subscription when I logged in. Can I use it on the new box to download another Observium professional edition and test my build before moving data while my production Observium is still operational?
