how-to convert from WebLogic web app server to tomcat web appl server

I've a BO XI 3.1 SP2.3 installation.

The web appl server (CMS and INFOVIEW) are on a Solaris WebLogic 9.2 box connecting to a Windows 2003 box (CMC and back end services).

I need to know the task steps on how to take that working environment and replace the Solaris WebLogic web appl server with Tomcat web appl services running on the same box as the CMC and back end services.

We're moving away from Solaris based WebLogic to Windows based Tomcat. I need task steps to take a working BOE XI 3.1 SP2.3 system and re-tool it to serve InfoView, etc from Windows based Tomcat.
