Hi Experts
I have a system on SAP R/3 4.0B I am wondering if there is a direct upgrade route to ERP 6 EHP 7 or if we would need to upgrade to R/3 4.6C then upgrade via SUM from there to ERP 6 EHP 7?
The OS/DB is DB400_V5R3
We would upgrade the OS/DB to the supported version then run the SAP upgrade directly after before beginning production operations again similar to a Windows/SQL migration. Has anybody done something similar? Does anybody have any better ideas? Downtime is very restrictive and the testing cycle is quite onerous so we would need as few steps as possible.
Thanks for you input.
