MDG Upgrade from Co-deployment to HUB

0 Kudos

Hello Experts,

My client is now looking for the upgrade of their MDG system from Co-deployment to HUB.

Current MDG version running is MDG 7.0 on ERP and the target new HUB will be S/4HANA 1909.

The challenge involved here is not only we are doing a upgrade from ERP to S/4, but we are also going from co-deploy to HUB. So conversion is very much required here. As we are still in the analysis phase, we just want to make sure that we capture all the points or any sort of restriction that we can face.

Please if anyone of you has already done like this activity ( like moving from Co-deploy to HUB), can you list dome some of the challenges which you think is going to create trouble.

There can be several challenges like:

1. Data Model changes across ERP and S4Hana

2. Data Quality mechanisms - migration of BRF rules, cross BADI codes

3. Workflow rules and setup

4. DRF setups
5. All the derivations and all the abap codes written needs deep analysis
