Move CS5.1 activation file to new partition of macOS 10.14.6

[_nemery]

I want to upgrade the main partition of my macOS to Big Sur. I have created a separate partition running 10.14.6 to run legacy applications such as CS 5.1. However, I am unsure about how to move my activation over from the main partition to the separate partition. I do not currently have access to my installation disk (and probably will not until the pandemic is over), so is there a way to accomplish this without it? Any help would be appreciated, thanks!

you need the installation file(s) and your serial number(s). 

to download the installation file(s) follow the directions, Download Adobe CS5.5 Trials: Direct Links (no Assistant / Manager) | ProDesignTools

and secure the files for future use.  they won't be available indefinitely.
