Are legacy systems really the end of the world? For many companies, they are business-critical technologies that keep operations humming and revenue flowing. But for all the bad press they get, you might think they’re set to be the downfall of business as we know it.
Are they? Not necessarily. Can they be? Absolutely.
But to fully understand what legacy systems are and why everyone is so concerned about them, we’ll have to dig a little deeper. This post will look at what a legacy system is, provide some examples, and examine the value, risks, and challenges associated with them.
Before we can discuss the risks and challenges associated with a legacy system, we have to establish what we’re talking about. It’s surprisingly difficult to find a widely accepted definition of legacy systems – which can make it challenging to determine if it’s an issue at your organization.
It’s been two years since SAP announced it would sunset support for its on-premise ERP. There are five years until the current deadline. In business terms, five years seems like a comfortable window for change – in the technology world, five years is practically an eternity. With what seems like all the time in the world to migrate, is starting your SAP S/4HANA transition really that urgent?
The short answer: Yes.
The longer answer: Seriously, what are you waiting for? There are several reasons not to put off an SAP S/4HANA migration, no matter how daunting it may seem.
Organizations around the world have built their businesses on SAP technology, an investment that has spanned many years. For those enterprises that started their ERP journey with SAP R/3 in 1992, the relationship is decades-long.
The success of any IT project that involves the migration from established, foundational technology to contemporary, cloud-based technology, is often determined by how well you integrate the old with the new.
The SAP S/4HANA migration train is still at the station, and — thanks to industry feedback — it’s there to stay. At least until 2027 when support for SAP ECC ends. However, this welcome respite is just a pause in what for many enterprises will be their most significant infrastructure upgrade in decades.
