Migrating from Aperture to Capture One 12

I have held on to using Aperture for as long as possible, but with the recent announcement that Aperture will no longer work with Catalina, I know I have to make some changes and I need help.

First, my Mac is 10 years old. I will be getting a new one this year. After looking at options to replace Aperture, I am quite sure I will be going with Capture One 12. I am no expert at any of this and need help with the following:

Does anyone know if Capture One 12 still has an import from Aperture feature?

If it does, will it work with my Aperture library as it is managed (not referenced)?

If it does work, when I import the Aperture library into a Capture One catalogue can that catalogue be referenced?

If that all works out, can I then delete Aperture?

And I guess the last important question is, if my new computer comes with Catalina, can I do any of this at all (do I need Aperture to run to do this migration)?

Sorry for all the questions, but at least they are all related. I have over 20,000 photos collected over10 years all with folder and album structures, keywords, and ratings. I am terrified of loosing all that work.

Thank you in advance for any help you can provide.
