I am new to Drupal, but I am trying to upgrade a site with the version 7.43 to 8, flowing these steps: https://www.drupal.org/docs/8/upgrade/upgrade-using-web-browser
After installing the Migrate modules and defining the source site, I have the following error message:
Source database is Drupal version 8 but version 7 was selected.
Source database is Drupal version 8 but version 7 was selected.
In my old site's database, the drupal_version table is empty.
I hope someone canAny help me. Thanks!?
