moving license from old pc to new

I just am setting up TT on my new computer. I was able to install the 2023 software but I can't find the license key for that version. I want to make sure I can import last years data to facilitate my returns for this year. How can \i get the key to activate this PC? or Will I be ablie to import the data (which I have moved to the new PC) just be installing the 2024 software and then it reads from the saved returns?
