SAP ECC End of Support 2027: What Your Options Are

By the A Softech SAP team | Updated November 2026

If your company still runs SAP ECC, the deadline is close. SAP's regular support for ECC 6.0 ends on December 31, 2027. That is just over a year from now.

The good news is that your system will not shut off on that day. You have several options, and not all of them mean rushing into a huge project. The hard part is picking the one that fits your size, budget, and timeline.

This guide explains the key dates in plain language, walks through your options, and ends with a simple 90-day plan.

What "End of Support" Really Means

Here is the part many people get wrong. Your ECC system will keep running after 2027. Nothing breaks overnight.

What ends is SAP's regular, mainstream maintenance. That is the standard package of fixes, updates, and help that comes with your current contract.

The risk grows slowly, and it shows up in a few ways:

• You get fewer updates and fixes from SAP.
• Your system may fall behind on tax and compliance changes, which matters most if you run in more than one country.
• Many companies will be trying to book the same experienced SAP teams at the same time. The later you start, the harder it gets to plan well.

So the deadline is not a cliff. It is more like a countdown that gets more expensive the longer you ignore it.

Check This First: Which Version Are You On?

The 2027 date covers the latest three enhancement packages of SAP ERP 6.0 (EHP 6, 7, and 8). It also covers CRM 7.0, SCM 7.0, SRM 7.0, and Business Suite powered by SAP HANA.

If you are on an older enhancement package, your mainstream maintenance may already have ended in 2025. Ask your IT team which package you run, and confirm your status with your SAP account team.

Your options

There are five realistic paths. Here they are in plain terms.

Option 1: Move to S/4HANA Before the End of 2027

This is the cleanest path. You finish the move before regular support ends, so there is no gap.

The catch is time. Based on A Softech's own project estimates, a brownfield migration can take 12 to 18 months, a greenfield migration 8 to 12 months, and a net-new public cloud setup 6 to 10 months. With just over a year left, a company that has not started yet will find this tight, especially for a brownfield move.

This option fits you best if you have already begun planning, or if your setup is fairly simple. You can learn more about ourS/4HANA migration services.

Option 2: Buy Extended Maintenance and Migrate by 2030

SAP offers extended maintenance for three years, from the start of 2028 to the end of 2030. It costs a premium of two percentage points on your maintenance base. One third-party analysis describes that as roughly a 9% increase over what you pay today.

Think of this as extra time, not a long-term plan. After 2030, you fall back to customer-specific maintenance. If you want extended maintenance, plan to decide before the end of 2027. If you do nothing, you move to customer-specific maintenance by default.

This option fits you best if your migration project is underway but will finish after 2027.

Option 3: Move to SAP ERP, Private Edition and Use the 2033 Transition Option

SAP has also announced a transition option for customers who move to SAP ERP, private edition. It runs through 2033. The rules are narrower than extended maintenance, and the offer is not open to everyone, so check what applies to your contract.

This option fits you best if you want a managed cloud setup with room to customize. See ourS/4HANA Private Cloud service for how this works in practice.

Option 4: Use Third-Party Support for ECC

Some independent companies offer support for ECC at a lower price. This can keep your current system stable while you build a business case for a move.

The trade-off is clear. You will not get new SAP updates or features, and you still need a plan to move to S/4HANA later. Before you choose this route, read your SAP contract carefully and ask what you give up.

This option fits you best if you do not plan to migrate before 2030 and your system is stable.

Option 5: Do Nothing

You can wait. ECC will not stop working. But after 2027 you move to customer-specific maintenance, and the risk, cost, and pressure will all rise as 2030 gets closer. We do not recommend this option for most companies.

Can you use what you already pay SAP toward the move?

Possibly. SAP runs two programs that let customers shift part of their existing spend. Both depend on your contract, so talk to your SAP account team before you plan around them.

Cloud Extension Program: Running since 2013, this lets customers move parts of their on-premise licenses and maintenance into cloud subscriptions, for example Ariba or SuccessFactors. SAP expects an expanded cloud investment in return. You can read the program criteria on SAP's site.

On-Premise Extension Program: This lets customers replace existing on-premise licenses and maintenance with selected solutions from SAP's on-premise portfolio, such as S/4HANA. The new maintenance must stay the same or go up. Here are the program rules.

If neither program fits, customers can also give up certain licenses and ask to end the matching maintenance without buying anything new. SAP then recalculates the discount on the remaining maintenance base. Details are in SAP'sdocument on other requests.

New rules for on-premise maintenance since July 2026

There is a recent change worth knowing about. SAP has agreed to a set of adjustments that make its on-premise maintenance and support practices more flexible, transparent, and predictable.

These changes took effect on July 10, 2026. They apply worldwide to all current and future SAP customers across all on-premise products. The commitment lasts 10 years from the date of the European Commission decision under EU competition law.

We will not go into the fine print here, because it depends on your contract. ReadSAP's official page and ask your SAP representative how it applies to you.

If you migrate: which path should you take?

There are three common ways to move from ECC to S/4HANA:

• Brownfield means moving your current setup over. It is like renovating the house you already live in. You keep your data, processes, and customizations, and update what needs to change.
• Greenfield means starting fresh. It is like building a new house. You redesign your processes and move only what you need.
• Selective data means moving only the parts you pick. It suits companies that want a cleaner system but cannot start from zero.

You also choose where the new system lives:

• Public cloud is hosted and standardized by SAP, so it is faster to set up.
• Private cloud is dedicated to your company and allows more customization.

A Softech supports all of these. See our SAP Public Cloud and Private Cloud pages to compare. If your business runs in East Africa, our localization services cover country-specific tax, currency, and reporting rules.

How to choose: a simple guide

• You have already started a migration project: Keep going, and consider extended maintenance as insurance if the go-live date might slip past 2027.
• You have not started, and your system is heavily customized: Plan for a longer project. Extended maintenance will likely be part of your plan.
• You want to move fast and are happy with standard processes: A greenfield move to public cloud is often the quickest route.
• You are not ready to migrate before 2030: Compare extended maintenance with third-party support, and read your contract before you decide.

Your 90-day action plan

You do not need every answer today. You need a clear next step. Here is a simple plan:

1. List every Business Suite 7 system you run. That means ECC, plus CRM, SCM, and SRM if you use them.
2. Check your enhancement package. Find out whether you are on EHP 6, 7, or 8, or an older one.
3. Pull your SAP contract. Note what you pay for maintenance today, and what your renewal terms say.
4. Pick a target go-live date. Work backward from it to see if 2027 is realistic.
5. Choose your path. Brownfield, greenfield, or selective data, and public or private cloud.
6. Decide on extended maintenance before the end of 2027. If your go-live may land after the deadline, do not leave this to the last minute.
7. Bring in an experienced partner early. A good assessment saves money later.

Frequently asked questions

When does SAP ECC support end?

SAP's mainstream maintenance for ECC 6.0 (the latest three enhancement packages) ends on December 31, 2027. Older enhancement packages already left mainstream maintenance at the end of 2025. Extended maintenance is available from 2028 to the end of 2030.

Will my ECC system stop working after 2027?

No. Your system will keep running. What ends is SAP's regular maintenance. Over time, the risks grow, such as fewer updates and a harder time keeping up with tax and compliance changes.

What is extended maintenance, and what does it cost?

It is an optional SAP offer that keeps support going for three more years, from January 2028 to December 2030. It costs a premium of two percentage points on your maintenance base. Check your own contract for exact numbers.

What happens if I do not choose extended maintenance?

You move to customer-specific maintenance, which is a thinner level of support. The same happens after extended maintenance ends in 2030.

Is SAP going to extend the 2027 deadline again?

SAP has said the 2027 date for mainstream maintenance is not being extended. There are other options around it, such as extended maintenance and the private edition transition option, but you should not plan around the main date moving.

How long does an S/4HANA migration take?

It depends on the size and the approach. Based on A Softech's estimates, brownfield projects often take 12 to 18 months, greenfield 8 to 12 months, and net-new public cloud 6 to 10 months. A detailed assessment gives you a more accurate number.

Can I use my current SAP licenses and maintenance spend toward cloud or S/4HANA?

Sometimes. SAP's Cloud Extension Program and On-Premise Extension Program let customers shift part of their existing spend. The rules depend on your contract, so speak with your SAP account team and your partner before you plan around them.
