IBM customers who are planning to port their applications from other DBMSs to DB2 should first contact the IBM Software Migration Project Office (SMPO) for a free general estimate for the project. The SMPO also offers a variety of migration services that may be of value to you during the porting process.
There are also a number of other Web sites that may be of value to you:
IBM developerWorks - Technical resources for DB2 and related products, as well as other IBM hardware and software technologies.
developerWorks DB2 library - This library can be used to find specific information about DB2 technology by keyword search. The library is constantly refreshed with new and updated articles and tutorials covering a vast spectrum of topics about DB2.
IBM Migration Toolkit - The IBM Migration Toolkit helps you migrate from Oracle (Versions 8i and 9i), Sybase (Versions 11 through 15), and Microsoft SQL Server (Versions 7, 2000, and 2005) to DB2 V8, V9, or V9.5 on any supported DB2 platform.
alphaWorks Emerging Technologies - This site provides a view of emerging technologies that IBM is pursuing and ways to access it.
Other resources - This Web page (part of this site) points to a number of resources (training, certification, consulting, documentation, and so on), and is updated periodically to reflect new resources and materials.
