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

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.

    You might want to consider the sap notes.

    Note 1007341 - SAP ERP 2004/2005 - supported ESS/MSS system landscapes

    Note 1034385 - BP ESS/MSS ERP2004 and ERP2005 on EPNW04s

    Good Luck!

    Hi Suresh,

    In my openion, it will be good if you go for new implementation, reason being as you mentiond ECC versionyou are on is 4.6c all the ESS applications are ITS based now a days all the application/iView for ESS are Webdynpro for Java or WD for ABAP based.

    Till the time the new portal ready you can continue with your currect one (No down time require).

    Most of the people are using this way. (Check the SDN for more details).

    Also chcek this migration guide, which will give you the basic steps required.
