Hi everyone,
We’re planning to patch/upgrade our SAP systems, and are currently reviewing some strategies.
This is what our systems look like at the moment.
ECC – NW7.0 Ehp2 SP 6 with ECC6 Ehp5 SP3
CRM, BI, EP – NW7.0 Ehp1 SP 7
PI – NW7.1 Ehp1 SP 5
Solman – NW7.1 SP12
The following are some of the options we’re considering:-
Option 1
Patch the systems to the minimum support packages so that SAP can
support us on any IE related issues
Option 2
Patch the systems to the latest support packages
Option 3
Full blown upgrade to 7.3 or 7.4 for all systems
Option 4
Partial upgrade of specific systems (PI, BI, EP) to 7.3 or 7.4 first,
then the other will follow on a later stage
Would be great if we could get your opinion/feedback on the options?
Especially any issues or limitations with the options?
Also is it advisable to patch the systems one at a time, e.g. starting with PI first, then maybe BI, then Portal etc etc
Do you think this will impact any dependencies between the systems?
