Hi All,

I've been trying to upgrade one of cient's instances. Every single time I run finish upgrading the db the site is starting to throw the following exception:

System.Data.SqlClient.SqlException (0x80131904): Violation of PRIMARY KEY constraint 'PK_tblBigTable'. Cannot insert duplicate key in object 'dbo.tblBigTable'.
The statement has been terminated.
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
