You are free to activate your license on as many systems as you need, given that you are the only user of the systems.

The license is assigned to a single user and not a particular machine. Therefore, you are free to install it on several devices as long as you are the only one using them. However, if you run a rental company or a venue with multiple stages, you must purchase one license for every rental unit or stage. Each rental unit or stage may have several machines under a single license, such as the primary and backup machines.
