I am looking for the project plan to migrate the SAP R/3 4.6c system to SAP S/4 HANA on-premise (1511). Please let me know the migration/upgrade steps and project road map to achieve.

Thanks,

Khadar

Hi, in addition to Joachim you have to have Unicode, otherwise you have to perform separate migration before S4.

But I advice to check "transformation" option (and not upgrade), because you have very old system and it's better to rebuild you business processes, implement new features and so on.

Well, that seems like a very long road to me.

1. Go to ECC6.0, latest EHP

2. From there, go to S/4HANA.

You really should consider staring with an new Implementation auf S/4HANA (greenfield approach) instead!

I agree with Joachim Rees.

The journey should be viewed as "Digital Transformation" and not mere technical migration.

Why are you going to S/4HANA 1511? You should go directly to S/4HANA 1610. Run the Maintenance planner to check if an upgrade is possible.

Thank you for all repliers....
My client do not willing to go for new installation of S/4 HANA. So I have given the below proposal.

1. Upgrade SAP R/3 4.6c to ECC 6 EHP6 with Unicode conversion.

2. ECC 6 EHP 6 to S/4 HANA conversion.

I hope this will be the right way to upgrade their R/3.

Thanks,

While adopting S/4HANA, Please have a look at "Digital Transformation" as Journey.S/4HANA should not be considered ONLY as TECHNICAL migration. It is much larger than that. Since the To-Be System is R/34.6, I see a lot of efforts if one goes the Upgrade and then System-conversion way.

Personally I would suggest, a Greefield NEW implementation of S/4HANA 1610/latest version instead. A Business Consulting and proper Business Case creation would help.

However If your client still insists for upgrade,

1. Upgrade SAP R/3 4.6c to ECC 6 EHP7 or EHP8 with Unicode conversion.

* Minimum required version for "System-Conversion to S4HANA is EHP7"

2. EHP6 is the First version available on HANA database, however EHP7 & EHP 8 has better HANA-Optimized functionalities.

Please feel free to connect in case any further details required.
