SAP ECC to S/4HANA migration

Move to S/4HANA with AI on the custom code and the master data.

Most of the effort in an S/4HANA conversion goes into custom ABAP code and master data. Skybuffer AI works on SAP ECC and S/4HANA side by side, so it carries that work before, during and after the move.

SAP ECC support timeline

End of 2027Mainstream maintenance for SAP ECC ends.
2030Optional extended maintenance ends, after three years at a premium.
2033Transition option ends, only for customers moving to SAP ERP, private edition.

Automation you build on ECC today keeps running on S/4HANA.

Where the migration effort goes, and where AI takes it over.

Your consultants still decide. The AI does the reading, the writing and the searching that usually fills the project plan.

ABAP Code Intelligence

Custom code analysis

Your Z code is documented and vectorized, so consultants can ask what each object does and what depends on it before deciding what to keep, rewrite or retire.

ABAP Code Intelligence

Custom code remediation

Functional consultants take each finding through specification to ABAP written for your target release, grounded in your development rules.

Duplicate search

Master data cleansing

Similarity search on vectorized master data finds duplicate customers, vendors and materials before business partner conversion.

MCP servers

Testing and short dumps

During test cycles, developers read ST22 short dumps, source code and metadata through MCP, from their own editor.

ABAP Code Intelligence

Documentation for every change

Functional and technical specifications, user guides and UAT scripts are generated for each change, in your own templates.

Assistants and agents

Automation that survives the move

Assistants and digital workers run on ECC today and keep running on S/4HANA after go-live.

Before, during and after the conversion.

  1. 1

    Know what you have

    • Custom code documented and explained
    • Duplicate master data found and cleaned
    • Assistants live on ECC for business users
  2. 2

    Rewrite and test faster

    • Remediated ABAP for your target release
    • Short dumps and source code read through MCP
    • UAT scripts generated with the code
  3. 3

    Keep the automation

    • The same scenarios and agents on S/4HANA
    • New S/4HANA scenarios on the same platform
    • One audit trail across both releases

Brownfield, greenfield or selective data transition.

Skybuffer AI connects to SAP ECC and S/4HANA at the same time, so it fits whichever conversion approach you choose.

Brownfield conversion

Carry your custom code across: analyze it, remediate what S/4HANA needs and retire what nobody uses.

Greenfield implementation

Understand what the old Z code did before you rebuild it on standard, and move only clean master data.

Selective data transition

Decide what moves with evidence from code and data, and keep automation running in both systems during the transition.

In production

Duplicate detection prepared master data for a move from SAP ECC to S/4HANA, and a critical ABAP backlog reached user acceptance testing within one month.

ECC to S/4HANA migration questions

How does AI speed up an SAP ECC to S/4HANA migration?

Mostly by shortening the custom code and data work. AI documents what your Z code does, writes the S/4HANA-ready version, finds duplicate master data before the conversion and drafts the test documents. Your consultants review and decide.

Can AI analyze custom ABAP code that has no documentation?

Yes. Code Intelligence reads the code itself, documents and vectorizes it, and answers questions about it in plain language, inside your landscape and on your own model.

How do we clean master data before business partner conversion?

Duplicate search compares vectorized customer, vendor and material records by similarity, so near-duplicates that exact-match rules miss are found and resolved before the conversion.

Do we have to wait for S/4HANA to use Skybuffer AI?

No. It runs on SAP ECC today, on-premise or from your own SAP BTP subaccount, and the same scenarios keep working after the move.

When does SAP ECC support end?

Mainstream maintenance ends at the end of 2027. Extended maintenance is available through 2030 at a higher fee, and a transition option runs to 2033 for customers moving to SAP ERP, private edition.

Does our code or data leave our landscape during the migration?

No. Skybuffer AI runs on SAP HANA in your data center or in your own SAP BTP subaccount, with the language model you choose, including self-hosted models.

Bring one program, one data domain or one test cycle. We will show what AI does with it, in your own system.
