Yes. I've been on OMS 10.2.0.5 for some time with a 10g database. I just upgraded to 11g yesterday. don't forget to run catupgrd.sql I'd do them separately though. Upgrade to 10gR5 Grid, then later, upgrade the repository.

This does not upgrade the database (that it creates). Can I upgrade the database to 11g instead? Thanks, Manjula
