Hallo, während des Update auf 5.6.4 bleibt die Aktualisierung bei der Datenbank Migration stecken:

Error  
Received the following error message:  
Could not apply migration (Migrations\_Migration1627). Error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`#######`.`#sql-7f7_2adcba`, CONSTRAINT `#sql-7f7_2adcba_ibfk_1` FOREIGN KEY (`orderID`) REFERENCES `s_order` (`id`) ON DELETE CASCADE)

Please try to fix this error and restart the update.

Wie kann man dieses&nbsp;Problem fixen?
