Hi experts,
Some questions in this link(google: Managing SAP ERP 6.0 Upgrade Projects and download PDF)
1. Is figure 5.3 in page 165 correct?
I think it should be
Temporary system: DEV 6.0
Productive system: DEV' 4.6C -> QAS 4.6C -> PRD 4.6C
2. Is this transport route possible?
"During this phase, you continue dual maintenance of the development
systems. You also transfer changes that you make in DEV' to DEV, and
transport changes to both quality assurance systems."
DEV' 4.6C -> DEV 6.0 -> QAS 6.0 -> QAS' 4.6C
If we modified some standard programs and transport between two different SAP versions, I think the programs can't work, right?
