Hi @Dominik Reinisch ,
Sometimes, restarting the migration assistant can help resolve temporary issues.
In addition you are still with something to do.
Check the Access database connection: Make sure that the Access database file (.mdb or .accdb) is accessible and that you have the necessary permissions to read from it. Verify the connection settings in the Migration Assistant to ensure they are accurate.
Check the SQL Server connection: Verify that you have a valid connection to the SQL Server. Ensure that the SQL Server is running, and you have the necessary permissions to create a database and transfer data to it.
Check for error messages: The Migration Assistant may display error messages or warnings in the log or output window. Check for any error messages or warnings and take appropriate actions to resolve them.
Best regards,
Seeya
