New Enterprise-Object of old one

Hello WO-Checkers,
is there an easy way to make a copy on Enterprise-Object and save this as a "new" Enterprise-Object? Because the only solution I found is this:
-------
User u = new User();
session.defaultEditingContext().insertObject(u);
u.setLastname(old.lastname());
u.setFirstname(old.firstname());
...
...
...
session.defaultEditingContext().saveChanges();

-------
And this solution is every else than a good solution :)

Thank you a lot
Peter M.
