Many organisations are deciding to migrate to SAP S/4HANA to become more agile and benefit from the digital transformation benefits inherent in S/4HANA. Here is what you should do to be successful.

As a current SAP ECC customer you have maintenance support for Core SAP ECC7 until the end of 2027 and an extended maintenance period until the end of 2030.

While there is still time to plan your migration, it’s never too early to migrate to S/4HANA.

S/4HANA offers a host of new benefits, including improved performance and access to real-time data from every part of your company. It is also many organisations first steps into the Cloud and an opportunity to become more agile, innovative, and competitive.


Migrating to SAP S/4HANA offers many opportunities – but it also poses several challenges. Here are four steps to take to reduce your risk and guarantee a smooth transition.


Start by interrogating your current SAP environment and the value of migrating to S/4HANA. In this step, you can decide what to move to S/4HANA. You can also identify which SAP systems you need to replace or retire. Now is also an excellent time to check those custom objects, chances are many have never been used.

Then, head over to to understand if S/4HANA can meet each of your specific needs. S/4HANA offers several line-of-business applications. You might find replacements for your current custom functionality and functionality your users want, but your current solution cannot accommodate.

A question often asked is, ‘does it make sense to migrate your existing environments to SAP S/4HANA?‘ The answer is to examine your existing environment critically and determine which pieces you want to migrate. You might find value in migrating your legacy environments, but deciding to leave these systems behind can also allow you to better leverage new business models and drive more value for your investment in Cloud.


Building a roadmap is essential to crafting a business case for your S/4HANA migration. A practical roadmap will be your best asset in convincing the current business that S/4HANA can meet their business needs and goals.

In this step, you need to interrogate your complete IT landscape and ask several questions:

  • Which S/4 HANA functions meet your needs (both business and IT)?
  • What current ECC components should you migrate to SAP S/4HANA?
  • How will changes to your environment impact third-party application and interfaces? Do you need to upgrade? Can you achieve the same outcome with S/4 HANA or other new generation SAP products?
  • Do your current systems have any custom or bespoke functionality that isn’t available in SAP S/4HANA? If so, what are your plans to resolve this?
  • How will you address the deficiencies in your gap analysis? Will you handle them internally? Do you need a partner who can provide a solution or an application to meet your needs?


Many customers ERP environments have been around for more than ten years. These older systems often haven’t been updated to support today’s agile business applications.

Recently, SAP has changed its underlying technology to allow for higher availability and performance. However, organisations that rely on ageing systems battle to take advantage of these benefits. Now might be an excellent opportunity to refresh your SAP landscape.

Migration is also an excellent time to reengage with business users about their needs and address gaps in the current solution. It’s essential to include the business in any decisions, buy in now will save a considerable amount of change management effort in future. If you can’t give the users what they want, they may go elsewhere and create shadow solutions which ultimately erode the value an SAP S/4HANA migration can bring.

With changes to how companies work bought about by Covid and other mobile and remote working impacts, SAP S/4HANA supports highly available, remote access. Consider this in your to-be architecture.


If you use an external hosting service, speak to them when you start your conversations with business users. Changes to your SAP environment could impact your hosting infrastructure and the managed services you currently receive.

Also, now is the time to address any third-party systems that integrate with SAP. You may have many business imperative applications and procedures that touch your SAP environment. You will be surprised at how many third-party applications and solutions have crept into your SAP landscape over the years. How will your migration to SAP S/4HANA impact these?
