What is your transition plan to S/4 HANA?

Explanation of Rev-Trac's change control processes

The clock is ticking for SAP customers to transition to S/4 HANA. Yet, we haven’t seen a stampede toward S/4 HANA. Indeed some organizations are still undecided or don’t have comprehensive migration plans.

So, what is the current situation?

Recently, several reports on SAP customer transition plans to S/4 HANA have been published. Among these are papers commissioned by ASUG, Rimini St, Resulting IT, SAP (IDC) and SAP Insider.

After reading the reports – and a commentary on one of them – it was difficult to come away with an accurate sense of the real state of play. Yet, the compiled survey results are worth sharing.

A little background

Firstly, it is important to be aware of potential biases in the results:

  • SAP sponsored the IDC report
  • Resulting IT is independent of SAP
  • Rimini Street offers 3rd party SAP support
  • SAP Insider and ASUG may or may not be independent
  • SAP Insider quote SAP as a research partner

Secondly, the commentary I read courtesy of Brightwork, states that ASUG’s 16% of the 38,000 to 45,000 existing ECC SAP customers running live on S/4 HANA is too high to be considered realistic.

S/4 HANA transition timing

Interestingly, whichever way you slice and dice the data, between 40% to 70% of current SAP ECC customers are not planning to transition by the deadline of 2025. Or, they simply won’t make it by then.

*Note that the Resulting IT report was the first to be published (around October 2018) and so things may have changed since then.

S/4 HANA Transition Method

There are three different approaches to think about when your organization is considering a move to S/4 HANA – greenfield, brownfield and bluefield (or hybrid).

MethodRangeResulting ITSAP InsiderIDC
Greenfield2% – 23%2%16%23%
Brownfield26% – 75%75%31%
Bluefield/Hybrid13%33%
Being planned23% – 44%23%36%44%

What we are seeing of our customers currently transitioning or intending to migrate in the near term, is that most have or will adopt a bluefield/hybrid approach.

S/4 HANA Deployment Method

SAP’s cloud offerings have always been a moving target. Perhaps this is why only two of the reports published SAP ECC customer S/4 HANA deployment intentions.

The results from both are close. However, with more than 50% of organizations intending to run all or some of their S/4HANA systems on-premise, don’t throw away those servers yet.

On-premise32% – 40%40%32%
Public Cloud13% – 44%13%44%
Private Cloud30% – 44%30%
Hybrid17% – 23%17%23%

Access to skilled consultants

The likelihood of a ‘skills crunch’ dominates the conversation when talk turns to the timing of a move to S/4 HANA. So, access to the right skills should be a key decision criterion.

According to Resulting IT

108 million consulting days will be required for all of SAP’s 40,000 ECC customers to be on S/4 HANA by 2025. This is based on a 9-month implementation with 15 consultants engaged on the project. Note: The Gartner report quotes 12-18 months for many transitions.

Since only half of SAP’s customers, at this point anyway, plan to move to S/4 HANA by 2025, only 54 million consulting days will be required. Still, to put that into perspective, that’s some 245,500 man-years.
