``` Ich habe jetzt mehrmals versucht, auf die neue Version zu aktualisieren. Ich bekomme immer wieder Fehler beim Update (Datenbankmigration). Es ist auch möglich, alle Website-Dateien vom FTP zu löschen. Neue Version hochladen. Und dann installieren. Kann ich das machen Und werde ich meine aktuelle Website / Produkte / Texte usw. behalten? ( Sie würden erwarten, dass die alten Daten aus der 6.0.0-Datenbank abgerufen werden) ``` ---

Hi vanlohuizen, wir vermuten, dass der Fehler aufgrund des op\_cache entsteht. Wir haben die Referenz auf SALES\_CHANNEL\_TYPE\_PRODUCT\_COMPARISON entfernt.  Wenn du das ganze lokal bei dir fixen möchtest kannst du folgende Änderungen bei dir einfügen: [https://github.com/shopware/platform/commit/6c418fdd7b4569f07c8133da470207ba05647377](https://github.com/shopware/platform/commit/6c418fdd7b4569f07c8133da470207ba05647377) Ansonsten wirst du die Änderungen mit dem nächsten RC automatisch bekommen. Gruß Oliver ---

Gibt es auch einen Lösung für die Folgende Fehler?

Klingt so, als ob eine mail\_template\_type\_id doppelt im System ist. Also am besten mal die Tabelle mail\_template prüfen. Den Eintrag löschen und danach das Update nochmal starten.   ---

Ich habe leider kein Glück. Ich habe einige zusätzliche Informationen hinzugefügt. Gibt es eine Möglichkeit, dieses Problem zu lösen? Ich finde es schade, dass bei einem Update so viele Fehlermeldungen auftauchen. ``` Error Received the following error message: An exception occurred while executing 'INSERT INTO mail_template (id, mail_template_type_id, system_default, created_at) VALUES (?, ?, ?, ?)' with params ["\xda\xaf\x66\x9c\xc1\xdd\x46\x70\xa8\x40\xe3\x69\x1f\x40\x4e\x39", "\xe2\xff\x06\x8d\xb2\xb2\x43\x85\xae\xf4\x72\xef\x88\xe6\x71\xc7", true, "2019-12-18 18:26:26.000"]: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`vanlohuizen_6`.`mail_template`, CONSTRAINT `fk.mail_template.mail_template_type_id` FOREIGN KEY (`mail_template_type_id`) REFERENCES `mail_template_type` (`id`) ON DELETE SET NULL ON UPDATE C) Please try to fix this error and restart the update.
