Hello Gurus, Doubt on gird software installation.. I have 11.1.0.7 RAC setup already running on my system and i decided to upgrade my crs/asm/db to 11gr2, in that case is it possible to install 11gr2 grid software alone while my 11.1.0.7 already running on my system? will there be any conflit? Please advise -Nagaraj -- //www.freelists.org/webpage/oracle-l
