Answer 1

Dear Peter, First thanks for your concern, and below the two classes after adding pair to. To get the classes before changes find the my comments that will tell you what to remove. [HierarchyRoot]

[Index("Code", Unique = true)]    
public class ABCClassification : BasicDefinition
{
    //Remove PairTo to get old version
    [Field]
    [Association(OnOwnerRemove = OnRemoveAction.Cascade, OnTargetRemove = OnRemoveAction.Clear, PairTo = "ABCClassification")]
    public EntitySet<ABCClass> Values { get; private set; }

}
[HierarchyRoot]

[Index("Code", Unique = true)]    
public class ABCClass : BasicDefinition
{

    [Field]
    public string ClassificationColor
    {
        get;
        set;
    }

    [Field(Nullable=false)]
    public decimal Percentage
    {
        get;
        set;
    }

    //Remove this to get old version
    [Field]
    public ABCClassification ABCClassification
    {
        get;
        set;
    }

}
