Trying to migrate to a new macbook air with an older OS than my current one...

I just bought a new Macbook Air 2025 and tried to migrate from my 2020 Macbook Air. The problem is, my 2020 has a newer operating system and its telling me that I cant migrate because the new machine has an older operating system than my current one. How do I do this???

Reinstall current macOS on the new Mac, then perform the migration during the first boot and setup.

There are other ways to do this, such as creating a new login with a different user on the new Mac and performing the update, then using Migration Assistant. (You’ve probably created and used the same login you want when you’re done migrating though, which makes this path a little more complex.)
