I agree. Let's move the question. How do I do that?
Are you a moderator on that site? If not you could flag for mod attention and propose the site to migrate with your flagging reason.
Site moderators or CMs can migrate questions to other sites single handedly.
I asked a question on SO and someone has pointed out (via a close vote) that it would be better suited to Super User.
In your particular case, you can simply copy body and title of your question, reask it at SE Super User, and delete your original question at SO.
The latter is important to avoid cross-posting.
IIRC SE Super User is a site listed in the standard close reasons to migrate a question at SO. Thus you can vote yourself for migration selecting that site, but that won't have an immediate effect to get your question migrated, it still needs five (or is it three meanwhile for SO?) users to migrate your question, so you have to wait1.
There are good reasons for this: Not all folks with CV powers participating the original site, might also have good in depth knowledge what's on-topic at the proposed target site.
We've even seen cases where site moderators or CMs got that wrong.
