How do I Convert (Upsize) an Access database to SQL Server?

The easiest way to convert an Access database to SQL Server is to use the Upsizing Wizard.

Step 1

• Preserves database structure, including data, indexes, and default settings. 
• Automatically converts Access validation rules and default settings to the appropriate SQL Server equivalents. 
• Maintains table relationships and referential integrity after you upsize.

Step 2

To run the Upsizing Wizard in Access 2000, on the Tools menu, point to Database Utilities, and then click Upsizing Wizard. To use the Upsizing Wizard in Access 97, you must first download the Microsoft Access Upsizing Tools 97 from the following Microsoft Web site:

http://www.microsoft.com/products/developer/officedeveloper/access/prodinfo/aut97dat.htm

To run the Upsizing Wizard from Access 97, on the Tools menu, point to Add-ins, and then click Upsize to SQL Server. If you have an earlier version of Access, you can do either of the following:

• Upgrade to Access 97 or Access 2000, and then run the Upsizing Wizard. or
• Use SQL Server Data Transformation Services (DTS) to import the data from your Access database to a SQL Server database. For more information about DTS and the DTS Import Wizard, see the “Data Transformation Services” and “Using the Import and Export Wizards” topics in SQL Server 7.0 Books Online. For an example, see the “Importing Data from an Access Database Example” topic in SQL Server Books Online.

Access 2000

In Access 2000, on the File menu, point to New, and then click New Project from Existing Database. This option creates an automatic data processing (ADP) application. This application automatically uses the SQL Server Desktop Engine (also known as MSDE 2000) or SQL Server as the server and uses the ADP file as the application. Note When you run the Upsizing Wizard from Access 97 or Access 2000 to SQL Server 2000, you may receive an “Overflow” error.
