Original code:

[HierarchyRoot]
public class BaseEntity : Entity
{
    [Field, Key]
    public int Id { get; private set; }
    [Field]    
    public Status Status { get; set; }
}

[HierarchyRoot]
public class MyEntity : Entity
{
    [Field, Key]
    public int Id { get; private set; }

    [Field(Length = 100)]
    public string Text { get; set; }
    [Field]    
    public Status Status { get; set; }
}

[HierarchyRoot]
public class Status : Entity
{
    [Field, Key]
    public int Id { get; private set; }

    [Field(Length = 100)]
    public string Text { get; set; }
}

New code:

public class MyEntity : BaseEntity
{
    [Field(Length = 100)]
    public string Text { get; set; }
}

I have tried all the remove/move/renameField hints, but they dont work, it says:

Unsafe actions:
  RemoveNode, Path=Tables/MyEntity/Columns/Status.Id
