Problem
You reached the limit or your unhappy with the performance or features of your database server, and you want to move to DB2. The transition can be simple with respect to your code, as it may be just a matter of changing a few lines of code for the connection string, and setting the correct compatibility mode in DB2. But how do you move your data?
Solution
IBM has published a data migration toolkit, that has been updated to work best with DB2 9.7. Make sure you have service pack 2 installed, which is the latest service pack available as of this writing.
If you are migrating from MySQL or PostgreSQL, enable the ability to do limits and offsets in the where clause with:
db2stop force
echo Set compatibility to 01 or 0F
db2set DB2_COMPATIBILITY_VECTOR=01
db2start
