It is available from a variety of sources, including Microsoft Office 2000 or later and the Microsoft Developer Network. For an introduction to and demonstration of using the Microsoft Access Upsizing Wizard as well as information on what to check prior to upsizing, design considerations, suggested troubleshooting techniques for common upsizing issues and additional resources for information, please refer to Q325017 How to Use the Microsoft Access Upsizing Wizard.

Upsizing an Access 97 Database to MSDE 2000

The recommended manner in which to upsize an Access 97 database to MSDE2000 is to use Access 2002 to load your mdb file and then use the Access 2002 Upsizing Wizard to migrate to MSDE 2000.

Using Access Data Projects With MSDE 2000

With the release of Microsoft Access 2000, an exciting new technology has been introduced: Access projects (.adp files), which allow you to develop true client/server applications from within the Access environment. Creating these project files differs from the traditional file-server development that Access developers have typically used, such as developing a database application with the Microsoft Jet database engine and saving all the database objects in a single .mdb file. Like an .mdb file, an Access project file also allows you to develop a database application in the Access environment, but instead of using Jet, you're natively using either Microsoft SQL Server or the new SQL Server 2000 Desktop Engine (MSDE 2000) as the back-end database. For more information on Access Projects (ADP's), refer to the following MSDN and Knowledge Base articles:

Introduction to Microsoft Access 2000 Projects and the MSDE 2000
This document lists the best sources of detailed information about Microsoft® Access projects (.adp files), which allow you to develop client/server database applications in Access by using either Microsoft SQL Server™ or Microsoft Data Engine (MSDE) as the back-end database.
