NOTES: One of the exciting new features in DB2 9 is support for installing multiple DB2 copies on a single system (including multiple copies of the exact same version). Also, on Linux-based systems, you can now choose your DB2 installation directory.

However, you must uninstall all copies of the DB2 9 test drive before installing the new DB2 Express-C 9 images.

The db2_deinstall script is no longer placed in the root of the install image, it is now located in /install. You should use db2_deinstall from Version 8 to uninstall Version 8 products, and db2_deinstall from DB2 9 to uninstall DB2 9 products.
