I tried out the built in Drupal 9.3 migration tool where it reads the Drupal 7 data and just imports it over. I have a bunch of non-migratable modules so an error did occur during migration. Is there a way to selectively migrate content types and taxonomy terms? I don't need everything, just some things.
And as for the data, my main concern is keeping the URLs intact to keep the SEO ranked pages. I'm guessing that would not be the same migration tool as that is the content itself?
