Any known issues for BW 3.5 upgrade to SAP EHP1 for SAP NW 7.0 stack 5

Hi all,

We are planning to upgrade our BW system from BW 3.5 to SAP EHP1 for SAP NetWeaver 7.0 Stack of 5.

We don't have SEM components.

Can anyone share the experince, lessons learnt and upgrade issues faced and etc?

Would also like to know the appropriate OSS notes related to this upgrade on BW perspective.

Advance Thanks.
