Existing database maintenance plans are upgraded and continue to work in SQL Server 2005. However, you will not be able to create new database maintenance plans by using SQL Server Management Studio. To view the maintenance plans in Object Explorer, expand Management, and then expand Legacy. You can migrate existing database maintenance plans to the new format by selecting Migrate from the context menu for any database maintenance plan. Because the new maintenance plan feature is not a direct replacement of database maintenance plans, some functionality might be lost after migration. Migrating a database maintenance plan does not delete the old plan, so you can test its functionality as a maintenance plan before removing the old plan.
