When you use Microsoft Access 2000 to open a database that was created in an earlier version of Microsoft Access, in most cases, the database is converted without difficulty. However, there are circumstances when objects and code in the older database may conflict with new features in Access 2000. Before you convert a database to Microsoft Access 2000, you should review the available information about conversion and compatibility so that you can be familiar with the issues that may arise. This article lists many of the resources available about conversion and compatibility.
