Upgrade Oracle 10.2.0.5 to 11.2

Hi everybody!

I´m planning to do upgrade on my BW Development that is running on oracle 10.2.0.5 to 11.2.

I have two more environments on this landscape, (BW QAS and BW PRD) both running on oracle 10.2.0.5.

Can I have any problem, working on a system that the database is different than other? BWD - running on 11.2 and BWQ, BWP running 10.2.0.5.

Regards,
