I'm currently trying to upgrade from v13 to v14.2.0 I am receiving the following error during the upgrade process of the database. Microsoft.Data.SqlClient.SqlException HResult=0x80131904 Message=Invalid column name 'key'. Source=Core Microsoft SqlClient Data Provider StackTrace: at Microsoft.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction) I'm unable to get past this. I saw another post recommending that I try the upgrade in unattended mode, but that doesn't seem to work either. Any assistance would be greatly appreciated.
