SAP ECC end of 2027: the clock is ticking – what now?

An ERP system with expiring maintenance is like an old machine works: It maybe still functions, but it costs more, brings security risks with it and is no longer up to modern requirements. This is exactly what threatens companies that continue to rely on SAP ECC 6.0.

Until 2027 everything stays as before. But after that it gets expensive – or risky.

Are you one of those who are already planning a migration? Or do you belong to the companies that are still unsure whether the switch to SAP S/4HANA is really necessary? Perhaps you're asking yourself whether alternatives exist that are more sensible in the long term?

One thing is certain: Whoever doesn't have a clear strategy now will, by 2027 at the latest, face great challenges.

SAP ECC: The support end is sealed

SAP has extended the support for ECC 6.0 several times, but now the end date is irreversible:

Until end of 2027: Mainstream maintenance for the SAP Business Suite 7.

2027 to 2030: Optional extended maintenance – with considerable additional costs.

From 2030: Definitive support end. No security updates, no further development.

But what does that mean for your company? Which options do you have – and which consequences threaten if you wait too long?

Three scenarios if you don't migrate in time

1. Extended maintenance: The expensive postponement

Companies that don't complete their migration in time can rely on extended maintenance until 2030. But that's no sustainable plan:

• Maintenance costs rise by an estimated 20 to 30%.
• A mid-sized company with 500,000 euros annual maintenance costs pays up to 150,000 euros more – every year.
• Additional costs for individual security patches and emergency measures.

Is this postponement worth it at all? Or is it more economical to initiate the migration now?

2. Third-party support: The supposed savings option

Some companies rely on third-party support, for example through providers like Rimini Street. These promise to support ECC 6.0 for a further 15 years – and that at lower costs.

• Up to 50% savings compared to the SAP maintenance fees.
• More flexibility in migration planning.
• But: No direct access to SAP innovations and new functionalities.

A real alternative? Or only a transitional solution without long-term added value?

3. Continued operation without support: A risky game

Whoever still relies on SAP ECC 6.0 in 2030 takes a high risk:

• Security gaps: Without new updates, the danger of cyberattacks rises.
• Compliance problems: Outdated systems often no longer meet the regulatory requirements.
• Technical limitations: No further development, restricted cloud and integration possibilities.

Can you afford these risks? Or is it time to make a clear decision?

The consequences of a delayed switch

Many companies underestimate the long-term consequences of a too-late switch. Yet it's not only about costs, but also about innovation capability and competitive strength.

1. Technological stagnation

Without SAP S/4HANA, your company stays at a technological state of yesterday:

• No IoT, AI or machine learning integration.
• Restricted cloud capabilities.
• Rising maintenance and adaptation costs.

2. Security risks and compliance violations

Without current security updates, the susceptibility to cyberattacks rises. At the same time, outdated ERP systems often no longer meet the newest regulatory requirements.

3. Competitive disadvantages

Companies that rely on S/4HANA early benefit from more efficient processes and better analysis possibilities. Whoever waits too long loses touch with the competition.

How does it continue now?

A current survey among SAP customers shows:

65% plan a migration to S/4HANA by 2027.

25% are unsure which path to take.

10% consider alternatives like third-party support or an ERP switch.

Where does your company stand? Do you already have a clear strategy – or are you still hesitating?

Conclusion: Act now instead of patching up later

The support end of SAP ECC 6.0 isn't a scenario for the distant future – it's imminent. Whoever doesn't act now risks rising costs, security risks and technological regressions.

Our recommendation:

• Develop a clear migration strategy.
• Examine alternatives like third-party support carefully for their long-term consequences.
• Calculate the costs and risks of a delayed switch.

The decision for or against a migration will decisively influence the future of your company. When is the right time for the switch? Now.
