You should have no difficulty moving from A2000 to A2003.
Both use exactly the same data engine (JET 4.0), and by default A2003 uses
the same file format as A2000.
Anything that worked in A2000 works the same way in A2003. It has
essentially the same functionality, right down to the same bugs. (Of course
the reverse is not true, i.e. the new stuff added to A2003 does not work in
A2000.)
There are a couple of new things you must adapt to, such as configuring
A2003 so you do not get multiple dialogs trying to convince you not to open
your database every time you attempt to do so.
There are also some new bugs to get used to. For example, in A2003, and you
have a subform that is based on a query, and the subform does not contain a
control for the field named in LinkChildFields, you can find A2003
constantly crashing (shut down by Windows.)
There are some also some display differences related to themed controls,
including bugs like this:
