Guidelines/Considerations for using SAP Pack vs SAP HANA Pack for doing bulk load in SAP

Hi Team,

We have requirement for moving bulk data from various source systems (SAP R/3 system) to SAP S/4 HANA.

We wanted to understand if there are any guidelines/best practices/recommendations as to when we should be using SAP pack vs SAP HANA pack.

Any information on this front would be helpful! Thank you!
