S/4HANA Migration on Windows Server - Best Option

[former_member242258]

Hello guys,

We have an ECC6 landscape with :

EHP7 FOR SAP ERP 6.0

SAP NetWeaver 7.4

Oracle 19c

Windows Server 2012 R2

We are currently checking what is our best migration option.

My questions are :

1) Are there limitations to have an S/4HANA system installed on a Windows Server 2016 LTSB or 2019 LTSC environment ? What would be the differences with Suse for example and would you recommend to perform an OS migration (from Windows to Suse) before considering to perform an S/4HANA migration ?

2) Would you recommend a greenfield approach if the acceptable downtime does not exceed 2 or 3 days ? Actually we have a small system with a data volumes of 2,7 TB. We would like to keep current data, configuration, and customizations. What would be the best approach to estimate the business downtime ?

3) When is the end of the mainstream maintenance of S/4HANA 2020 ? I found 31.12.2025 in the PAM but it seems strange to me that ECC6 mainstream maintenance ends in 2027 and S/4HANA 2020 in 2025. Maybe the information is not up to date in the PAM.

Thanks a lot for your help.
