DraftSight Basic License Control

We will be purchasing two DraftSight Basic licenses sometime this year (for plant drawings only). After we purchase the two licenses and later we decide to move the license to another computer or if we upgrade computers, is the process simple or am I going to have a nightmare getting DraftSight Basic running on another computer? Normally I am used to returning licenses, uninstalling the software, download the software on another computer or a new computer and then activate the license. Please tell me this is going to simple and not some convoluted nightmare! We only need the basic DraftSight because we use SolidWorks for everything else. Our 2D drawings of the plant were simple using the free version.
