What will happen if??

[belton72]

I want to test a new machine by installing the attendent console and connecting to the arc express server. I have two attendent licenses.
I intend using a trial license to test on the new machine.
After testing, I want to remove the new machine and reconnect the old machine with the valid license again. Will I be able to connect it back without having license issues on the old machine?
I.e. should it be still be activated.
