EF Code-First Migration - Ignore Property

I have a simple poco class that has an enum property (it is necessary that I still have the code that first created the enum lookup table). I do not want the migration generator to add this column to the database. Is there an attribute or some other way for the transition code to know to ignore the property?

Example:

public class MyPoco
{
    public int MyPocoId { get; set; }
    public int MyPocoTypeId { get; set; }

    public MyPocoTypeEnum MyPocoTypeEnum
    {
        get { return (MyPocoTypeEnum)MyPocoTypeId; }
        set { MyPocoTypeId = (int)value; }
    }
}
