When you convert a previous-version Microsoft Access database that has linked tables, make sure that the external tables are in the same folder that they were originally in. If Microsoft Access can't find the tables that are linked to a database that's being converted, you won't be able to use the converted database. Once you convert the Access database, you can move these tables and use the Linked Table Manager to re-link them. Converting a database that has tables linked to it does not convert the linked tables.
You can also convert a previous-version Access database by importing its database objects into a new Access 2000 database. You can use this method if you don't want all of objects in the previous-version database to exist in the Access 2000 database.
