Upgrading 4.0B to ERP 6.0
I need to upgrade an SAP system from 4.0B Oracle 8.0.4 on HPUX 10.20 to ERP 6.0 Oracle and on AIX. I have a few questions:
1. Do I need to upgrade to a minimum level (kernel patch, R3Load etc.) in order to use the OSDB migration tools?
2. For a heterogeneous migration to the AIX, can I install 4.0B/Oracle 8.04 on AIX 5.x release, do the migration and from there or is there a better way to do this ?
3. Do I need to do a 2 step upgrade of Oracle from 8 to 9i to 10g ?
4. Where can I find documentation on the migration and upgrade as there is no more information less than 4.6C in the service marketplace?
