Getting Error from Dynamics CRM 2013 to 2015 Upgrade

Hi,

I get the following error when upgrading on a new server.

CRM 2013 SP 1 Rollup 4 (6E.1.4.0145) SQL 12 Collation : Turkish_CI_AS

CRM 2015 (7.0.0.3543) SQL 12 Collation : Turkish_CI_AS

InnerException:

Microsoft.Crm.CrmException: Error installing sp with name=p_DeleteAttributeFromIndexById
Must declare the scalar variable "@indexId". ---> System.Data.SqlClient.SqlException: Must declare the scalar variable "@indexId".

Any ideas on this issue ?

Thanks.
