                    Id = c.Guid(nullable: false),
                    Weight = c.Single(nullable: false),

                })
            .PrimaryKey(t => new { t.PatientMedicalDataId, t.Id })
            .ForeignKey("dbo.PatientMedicalDataEntities", t => t.PatientMedicalDataId, cascadeDelete: true)
            .Index(t => t.PatientMedicalDataId);

        AddColumn("dbo.PatientDataEntities", "PatientDataFilePath", c => c.String());
        //Here I need to move data from the old Weight column to the Weight column on the newly
        //created table and create the id (Guid) and the foreing key before …
