Which installation options are supported per release version?*
ABAP Java
1. PI Dual Stack (all releases)
+ Functional scope - Higher TCO
- No innovations for ABAP
Java
2. PI Java only (since release 7.3)
- Functional limitations + Lower TCO
+ Performance
* simplified illustration, excluding SLD, tools, optional non-central adapter engines, etc.
3. Process Orchestration (since release 7.31)
++ Functional scope + Lower TCO
+ Performance
Java Java
PI Java only BPM incl. BRM
How to get from PI to Process Orchestration?
Migration versus in-place upgrade
Migration (side-by-side deployment) In-place upgrade
Pros Minimized downtime Clean up of scenarios
Less hardware requirements Defined end date
Cons Basic setup from scratch
More hardware needed, higher maintenance and operational costs
Rollback risk
Not possible for all installation options
