Hi!
I would like to upgrade a SAP R/3 system to EHP4 in one step.
Where can I find the documentaion describing:
- technical description of whole process
- generation of XML stack file from SAP Solution Manager
- which tool (SAP EHP Installer, Upgrade Installer, etc.) should be used?
- relevant SAP notes
Any helpful information will be very appreciated.
P.S. colleague of mine has a problem after generation of stack file from SOLMAN within Upgrade.
The error tellls that the stack is invalid...
regards
Holger
