How to migrate a single DSO-Object from one system to the other

Hello experts!

I need to migrate one DSO-Object from one system to the other.

In our BW system there is a DSO-object u201CDSO1u201D supplied from PSA

2LIS_11_VAITM (orders) in Delta-mode from SAP EPR-System in

daily extracts. DSO1 has aktiv data and change Log. PSA-Records of

2LIS_11_VAITM are daily deleted.

Now DSO1 must be transferred in the other BW-System.

The task is to migrate DSO1-Object with data and change log and switch

delta extracts from ERP to BW2 with no dataloss.

What is the best way to accomplish this?
