Although I'm not a Racket core developer I tend to have a dozen versions of Racket installed

I have at least that many installed, myself.

For what it's worth, I've previously suggested including migration in the installation process with a feature request over on GitHub:

[Feature Request] Automatically prompt users to migrate packages on installation

**Is your feature request related to a problem? Please describe.** When I was a… new user, I had no idea `raco pkg migrate` existed, and I didn't know about DrRacket's equivalent "Copy from Version" feature. I wanted to keep Racket up-to-date by installing new versions, but whenever I updated Racket, it always broke my packages! I was frustrated. Once I learned I could easily migrate packages, I was happy! But other new users may have the same problem I did. In fact, on the Racket Discord server, jimpjorps wrote: > it'd be a nice thing to prompt for, my first version was 8.0 and I flailed for a little bit when I upgraded to 8.1 because I thought I had to manually reinstall everything in raco before noticing Copy from Version So I'm not the only one who had trouble! **Describe the solution you'd like** The installation process should prompt the user when at least one existing Racket installation is detected, asking them if they'd like to migrate the packages from any of those installations. If they say no, the script can mention that the packages can be migrated at any time if the user wishes through a `raco pkg migrate` command; the graphical installer can mention "Copy from Version" in DrRacket. **Describe alternatives you've considered** DrRacket could have a pop-up which appears on the first run after upgrading, asking users if they'd like to migrate their packages from the previous installation. However, this would not help people who install using the command-line installation script. **Do you want to contribute to this feature** Yes, I could help!
