Requirement (Designed for Microsoft® Windows® Logo)
Your application must migrate seamlessly from Microsoft Windows 98 to Microsoft Windows NT 5.0.
If an application is installed on Windows 98, and the operating system is upgraded to Windows NT 5.0, the application must remain fully functional after the operating system upgrade.
If this is not the case automatically, the application vendor must develop and make available to users a Migration DLL as described in the Windows 98 to Windows NT 5.0 Migration Kit and the Migration Extension Interface Reference.
The Migration DLL should perform all tasks necessary to make the Windows 98 version of the application functional on Windows NT 5.0 after an operating system upgrade. This includes modifying or adding new registry entries and copying new files to their proper locations on Windows NT 5.0.
This Migration DLL should be tested by installing the application on Windows 98 and then upgrading it to Windows NT version 5.0 or later using the rules described in the Windows 98 to Windows NT Migration Kit (to be available with Windows NT 5.0 Beta 1) and the Migration Extension Interface Reference.
