SCM APO Migration-PPDS / gATP/ to S/4 HANA Cloud

[hari_ram]

Dear SCM Experts

One of the Client wanted to migrate to S/4 HANA Cloud from ECC System-on Prem, There are some queries regarding the APO migrations from the current SCM Landscape since already current SAP ECC system -on Prem is connected with SCM APO Landscape

Following are the queries

1.How to migrate the existing SCM -APO -DP/SNP functionalities when their ECC system migrates to S/4 HANA Cloud and how the SCM landscape should be ?

2 .Also for APO -PP/DS, gATP to S/4 HANA Cloud with embedded PP/DS, gATP functionalities

Could you please let me know how the landscape should be in this case for the customer using APO DP/SNP functionalities and APO -PP/DS, gATP when they migrate to S/4 HANA Cloud without impacting the current functionalities in APO system.

3. Additionally the client also wanted to know how the existing APO-DP /SNP functionalities will support if they migrate to IBP cloud

Kindly suggest

Thanks

Hari
