JDE World 7.5 and AS400 upgrade

I am trying to upgrade an AS400 v520 running V5R3 to a new Power6 machine running V5R4. Will JDE World v7.5 have any problems with going to V5R4?

jmoseby,
You should visit the Oracle support site and search for IBM V5R4 and World type documents for guidelines. An acquaintance with a 520 recently upgraded his OS to V5R4 from V5R3, but he is running World A7.3 CU 10. I don't recognize the name World 7.5.
