Kenan, I think this is not such a bright idea as stressed by the other gents. I have successfully done the LINUX migration from PA-RISC to LINUX which also included a DB upgrade from PA-RISC TO ITA an application upgraded to 11.5.10.2 and then a DB upgrade to 9208 to 10GR2. I had major non DBA related technical issues with the OS setups; an incomplete 11510 software set provide by Oracle; that I got around and now has been implemented in production. I worked non-stop 32 hrs on the implementation weekend to get this implemented and ran into an interface issue on prod night which was resolved, all I am saying it is hard for 1st and 2nd iteration but you have to go through the process with a fine tooth comb, and that there is light at the end of tunnel.
