Checklist Before HANA Upgrade (Brownfield)

[N_YILMAZ]

Hi SAP experts,

I have a customer who will be transitioning from SAP ECC to SAP HANA. A brownfield migration is planned. In this context, what is the easiest way to identify the developments and enhancements made in the ECC system? What should I do to adjust these developments after the system is upgraded to HANA?

I've gathered some information through research, but I'm looking for comprehensive knowledge. I'm open to your valuable suggestions.

Kind regards,
Nedim YILMAZ

Hi Nedim,

I agree with Thomas, and just adding the overview note to deploy Readiness Check and enable various functions. 
2913617 - SAP Readiness Check for SAP S/4HANA

For the customer code analyze, please choose from two options:
2185390 Enable Custom Code Analysis via Custom Code Analyzer (SYCM) BC-DWB-CEX
2781766 Enable Custom Code Analysis via ABAP Test Cockpit BC-DWB-CEX

Best regards,
