We are going to upgrade to SAP ECC 6.0 (technical upgrade only) and one interfacing application is also being upgraded by another department. Our integration broker is Java Composite Application Platform Suite (JCAPS) 5.2. I have been asked if, from an integration perspective, we should do the ECC 6.0 upgrade before or after the interfacing application is upgraded.
As the ECC 6.0 upgrade is technical only and thus covers an upgrade to the components SAP Basis, SAP R/3 4.6c, and patch level 0048, should it make a difference? All application-related functionality will remain unchanged.
