Automapper exception when converting object with inheriting members

[impeham]

I have the following objects:

public class Parent
{
	public BaseChild Child {get;set;}
}

public class BaseChild
{
}

public class ChildOne : BaseChild
{
	public string Member {get;set;}
}

"Parent" is mapped to a "Parent2" type from a different module (which has the same member BaseChild).

Mapper.CreateMap(typeof(Parent), typeof(Module2::Parent2));
Mapper.CreateMap(typeof(BaseChild), typeof(Module2::BaseChild));
Mapper.CreateMap(typeof(ChildOne ), typeof(Module2::ChildOne ));

I'm creating a Parent object:

Parent parent = new Parent
{
	Child = new ChildOne { Member = "Test" }
}

And try to convert:

object parent2 = Mapper.Map(parent, parent.GetType(), typeof(Module2::Parent2));

I get the following exception from auto mapper: ---------- {AutoMapper.AutoMapperMappingException: Missing type map configuration or unsupported mapping. Mapping types: ChildOne -> BaseChild Test.ChildOne -> Test.BaseChild ---------- I need this mapping to work in order to be able to convert objects from a new "Parent2" type (in the 2nd module) to an old one. How do I make it support inherited types of members in a converted class?
