Domino 7.0.2 install with IM 7.0

I am presently upgrading my servers for the DST. It recommends in the Deployment Guide DST 2007 that the Domino servers would handle the Java if the servers were upgraded to 7.0.2 FP1. I upgraded the server running IM 7 to 7.0.2 and it crashed and burned. I uninstalled 7.0.2 and re-installed version 7.0.0. It is now working fine. Is there a problem with the upgrade? Should I have uninstalled IM7?Thanks for your time.
