I’m migrating from Drupal 7 to Drupal 9 and am having an issue with my source files getting found with the upgrade_d7_file migration. My public files directory for my source site is not ‘sites/default/files’. It’s a multisite instance and it’s public file directory is ‘sites/example.com/files’. I have exported the configuration generated with migrate-upgrade –configure-only and can change the source_base_path value, then import it and see changes, but ‘sites/default/files’ gets added to the end of whatever I put into the source_base_path value. I do have my public files system path defined in ‘admin/config/media/file-system’ of the source site.
Is there a place to set the default path to start with something other than sites/default/files for the source site?
Thanks
