Can Poser Pro 11 be installed on more than one machine?

I have one license of PP11 installed currently on a workstation. I've just purchased a "new" workstation and am wondering if I can install Poser Pro 11 on the new one with the same serial number [with the understanding I will only use one machine at a time]? Or do I have to deactivate the PP11 install I currently have and reactivate it on the new machine? The manual does not seem to be too clear about this and I'd rather not break my licensing. The manual also isn't too clear about how to do this.

I also have a PP2014 install I will be moving to the new machine. do the same rules apply? Links to docs or howto do it would be most appreciated.

Thanks in advance
