What is the better way to migrate data during APO carve-out: selective data copy or initial load?

[dmitriikarpov976]

Hello all,

We need to carve out a part of a global APO system to a local hosting. Most of the master data is maintained in a local ERP, which makes it less complex. The question is, should we do a selective data copy to the new system or better run an initial load from ERP? Theoretically, the options seem very similar, but does anybody have practical experience and can share how it really works? What are the risks of these two approaches and what are key factors to make a decision in favor of any option?

I would go for:

1) an empty "shell copy" of APO (do not copy data - only settings, programs etc.)

2) do the initial sync with ERP once back connected.

Reason is more on the CIF integration and document numbers: if documents and data are migrated / reloaded into the target ERP and they are getting different document numbers / using different ranges etc. you will have a mismatch in APO LC which is not easy to repair. We had these issues even with system copies from PROD to TEST and we had to wipe out the entire database / LC in APO to re-initialize.

For DP you can use InfoCube etc. to store / restore data or re-initialize them too from your future EDW system where the carved-out APO is being placed into.
