Hello Gurus, Metalink Certification doesnt say if 10gR3 is certified with 11i , but Oracle is releasing security patches for 10.2.0.3 version as well, meaning that it must be certified. My question is - Has anyone upgraded to 10gR3 from 10gR2 on an 11.5.10.2platform? and If yes, whats the metalink document no. Thanks Navdeep
