SwagMigrationAssistant says that everything is migrated and it is now indexing. However, there is only one product migrated (out of 550), translations are made into categories. All is mess.

From the log:

Hallo dbugg,  
wir sind auch am Migrieren und der Shopware Support konnte oder wollte mal wieder nicht helfen, obwohl wir die Evolve Version haben. Hast du Insights, die du teilen kannst, da wir gleiche Fehler haben, wie du. Das wäre super. Vielen Dank.
