Is it possible to copy Photoshop CS3 from one imac to another

I am a professional photographer with my own studio. Several years ago I changed to iMac xfrom being PC based because I loved Aperture (and still do!).My studio imac is trying to update to the latest 64 bit version ofOSX but I know that Aperture won't work and it is a vital part of my workflow which I don't want to lose or change ( getting too old for change! )However I do have an olderback-up iMac with Mojave installed which works with Aperture and Adobe Bridge CS3.but not CS3 Photoshop! To make matters worse I can't find my installation disk but I do have one for CS2 but when I try to install CS2 or run CS3 I get a pop-up box saying that my licence has expired and to contact Adobe which I did today they told me that all support for CS ended 13 years ago and there's nothing that can be done. My main iMac does haveCS3 on and it works but I have also got CC on which I use daily. So my question is: can I copy CS3 from my main iMac and then I will be able to upgrade to the latest version of OSX and install it onto my back-up iMac thus keeping my workflow with Aperture?
