Hi so I have read the documents Drupal 7 to 8 but I have questions and errors about migrating from Drupal 7 to 8. So here are the steps I take to try and migrate, maybe someone can help spot where I go wrong:
- Set up blank Drupal 8
- Enable Migrate Modules
- Import D7 database and public files
- I get warning that I am missing 72 missing upgrade paths but continue
Once I get to the main page, my content has been imported but my subtheme (a bootstrap subtheme) is missing, along with my template files, css, and js. When I try to upload bootstrap theme and install it I get an error:
“DrupalCoreConfigPreExistingConfigException: Configuration objects (bootstrap.settings) provided by bootstrap already exist in active configuration in DrupalCoreConfigPreExistingConfigException::create() (line 65 of core/lib/Drupal/Core/Config/PreExistingConfigException.php).”
Is there a different approach to upgrading? Willing to use Drush instead of the UI. And how to I transfer over my subtheme?
Thank you in advance!
