We recently upgraded and migrated our BW 7..02 to BW 7.40 on HANA platform using DMO successfully. Major emphasize consider from technical front is to get BW system ready for business usage immediately after all SAP Basis and BW/HANA post DMO activities completed.

This is a challenging and required expertize on SAP Basis and BW front and understanding of all reporting and tools available in BW 7.40.

In each step mentioned in our step by step technical sheet consolidated and created by mutual effort of Basis and BW/HANA teams as a combined template for each post DMO effort.
