Is there any kind of documentation to help me get started migrating my subClasses to partial classes?
No, there is no docs for this. But it's quite simple:
Take your subclass, which should look like this:
public class MyCustomerEntity: CustomerEntity
{
...
}
then change it to:
public partial class CustomerEntity
{
...
}
and that's it. Now remove any reference to the subclasses in you business/gui code and use the base class instead. A simple find/replace should be enough.
