as400 a8.3 v5r4 to v7r1

  1. Upgrade A8.3 on V5R4 to same instance (A8.3) on V7R1

    Hello, I have a client who is running JDE A83 on AS400 V5R4 and want to migrate to V7R1. They are out of maintenance contract with Oracle and therefore cannot use the Oracle Universal Installer (OUI) to perform this upgrade. Has anyone done this migration before ? Appreciate if you can share any...
