Hallo zusammen,

beim Update der Datenbank von 5.2.12 auf 5.2.13 bekomme ich folgenden Fehler:

&nbsp;

Error

Received the following error message:  
Could not apply migration (Migrations\_Migration797). Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ‘frontend/salutation-1-mr-45’ for key ‘namespace’&nbsp;

Please try to fix this error and restart the update.

Response

```
 {"valid":false,"errorMsg":"Could not apply migration (Migrations\_Migration797). Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'frontend/salutation-1-mr-45' for key 'namespace' "}

```

Hat jemand eine Idee wie ich das lösen kann?

Viele Grüße

Stefan
