Lightroom 6 from iMac to another iMac

[Ivan154A]

In 2013 I bought my first iMac. I also installed Lightroom 6.

Now I'v bought another iMac and removed my old iMac. Can I bring the old Lightroom via Adobe over to my new Imac? How do I do it?

"IF" the new iMac has Catalina or newer operating system installed you won't be able to install Lightroom 6. Even though the Lightroom 6 program is 64-bit, the installer is 32-bit, and the operating system will not run it.
