SRM S4/HANA Integration with non SAP systems

Hi Experts,

We are currently using SAP PO 7.5 for S4/HANA - SRM integration with various non SAP/SAP applications.

Currently our management replacing SAP PO using SAP Event Mesh & SAP Integration Suite.

Could you please suggest me what are SAP Event Mesh options and strategy to replace SAP PO using SAP Cloud Integration. Thank you!
