Upgrade path for ESS/MSS business package while upgrading to ECC 6.0

24 Views

Hi All,

We have a scenario where SAP Enterprise Portal 7.0 SP 18 is currently running with SAP ECC 4.6C. SAP ECC is being upgraded to SAP ECC 6.0 and consequently we have a requirement to upgrade to the latest ESS/MSS business package. In a scenario like this what is SAP recommended approach for ESS/MSS upgrade? My questions are

1) Is a direct upgrade of ESS/MSS possible? If this is possible, then how will it be done on a production system with reduced or no downtime?

2) Should ESS/MSS business package be deployed and configured afresh after removing/undeploying the existing version of ESS/MSS business package? If this is the case how would the earlier customizations be restored?

3) Is there any other approach?

Thanks in advance.
