This presumes you want all Oracle specific schema elements.  He just wants
to move his application specific schema which many just be using a few
elements.  This is not at all so monumental a task.  Most likely the
matchingRules and syntaxes already exist and it's just a matter of creating
the objectClasses and attributeTypes which can be done immediately.

We have everything in place even to do this dynamically by adding these
schema elements even without stopping the server.

I have to write more user level information about the dynamic schema
subsystem.  I should have done this after writing it and we're paying for
that since not many people know what this thing can do.
