I'm trying to migrate a Drupal 7 website to Drupal 8. I have installed on the same server those two websites. Drupal8 version is empty. On the Drupal 7 website, more than twenty contrib modules are installed, like LinkIt, PathAuto, Token... I downloaded with Composer the D8 version of those modules. I installed them without any configuration. I followed the upgrading process on my D8 website, but the process cannot see installed modules on D8 version and told me that LinkIt or PathAuto won't be upgraded.
How can I fix it? Is there a solution to migrate configuration datas for these modules?
