It's certainly possible. The Migration Wizard is a bit hit 'n' miss to
be honest as I wrote it without ever migrating a database except for the
odd test using Northwind/Biblio.
Is it possible to get a schema only copy of your mdb file to look at
please?

We do sort of assume there are no \n's or \r's in your object names...
