Removing 10g CRS and Database Server Software after 11g Upgrade
                    
Can someone point me in right direction, please?  I have successfully upgraded my 10g RAC environment to 11g.  The old 10g $ASM_HOME doesn't exist now but the old 10g $CRS_HOME and database $ORACLE_HOME do.  What is the correct way to delete all the old 10 software?  A coworker had some issues with this but that was on Solaris x86; I'm on Sparc.  Since the oraInventory is now being actively used by 11g, will a 10g removal do anything to it?
