Migration approaches

Brownfield, greenfield or selective: TSP runs all three

The right approach depends on what’s in your system and how much of it you want to keep. We recommend one from your Phase 0 findings and reuse completed work wherever it holds.

  • Brownfield conversion

    Convert your ECC system to S/4HANA, keeping configuration, custom code and history.

  • Greenfield

    Start a new S/4HANA system on standard processes, moving only the data you need.

  • Selective data transition

    Build a new S/4HANA system and carry over chosen data, company codes and history.

How it works

How a TSP migration runs

  1. Assess

    A fixed-scope Phase 0 reads your ECC system and settles the approach, the downtime window and the plan your steering committee funds.

    About Phase 0

  2. Prepare

    Custom code is sorted into retire, rebuild or keep, and data cleanup starts early. TSP ARIA Project captures requirements from your workshops and documents, so none get lost between teams.

  3. Convert and rehearse

    Mock conversions on copies of your system, each one reconciled against the last, until the numbers match and the timing fits your window.

  4. Test

    Automated regression suites are built alongside the migration, with TSP ARIA Test generating test cases from your SAP configuration. You reuse them for every SAP release after go-live.

  5. Cut over and support

    A rehearsed cutover in the planned window, then hypercare until your teams are settled, and application management afterward if you want it.

How much custom code can we keep on S/4HANA?

More than most teams fear, and less than they have today. A large share of custom code in most ECC systems is rarely or never used, so the first step is retiring it. TSP sorts the rest by usage and value: keep what sets you apart, rebuild what S/4HANA changes, and move extensions off the core where that pays off.

FAQ

Questions about ECC to S/4HANA migration

Straight answers to what SAP leaders ask us most.

Talk to an SAP expert

How long does an ECC to S/4HANA migration take?

It depends on your scope, how much custom code you carry, your data volume and the downtime your business can accept. A Phase 0 assessment turns those into a realistic timeline for your system, with first findings within two weeks.

How much downtime should we expect at cutover?

Your cutover window is planned, rehearsed in mock conversions and sized before go-live, so there are no surprises on the weekend itself. Where the business can’t stop for long, downtime-optimized conversion methods can shorten the window.

Who owns data cleansing?

Your business owns the data and decides what’s correct. TSP runs the cleansing process, the tools and the reconciliation, and flags issues early. Cleanup starts during preparation, well before the first mock conversion.

Can you migrate us to RISE with SAP or to our own cloud?

Yes. TSP migrates to SAP S/4HANA Cloud Private Edition under RISE with SAP, and to S/4HANA on premises or on Amazon Web Services, Microsoft Azure or Google Cloud.

Can you take over a migration another partner started?

Yes. Project recovery starts with a short review of what’s done and what can be reused, then a plan to reach go-live. See project recovery.
