We have found one software suitable in our database for this conversion.
If any kind of mdb to gdb conversion is possible, it would be export of Microsoft Access databases (.mdb) to one of the known .gdb databases, something that should be doable. If MS Access does not suit your needs when it comes to export of file types, you will have to rely on some 3rd party converter for this.
