AIX 6.1 and Oracle 9.2.0

Hi All,
I need to update some AIX servers from 5.2 to 5.3 OR 6.1 .
The management is pressing for 6.1, but on our systems runs Oracle 9.2.0 .

I couldn't find any clear warning about the possibility of compatibility issues between AIX 6.1 and Oracle 9.2.0 but, on the other hand, I couldn't find any explicit document saying "Oracle 9.2.0 works on AIX 6.1" .

According to IBM website AIX 6.1 is capable of running any (well written) application from AIX 4.3 to 5.3 ...

Someone had any experience on this?
Thank you in advance for any help!

Regards
