Security gets weaker by the dayĪ data breach can cost a company dearly, and legacy systems are more vulnerable to hackers than newer systems. Companies with customer data need to maintain well-governed records, which is much harder (if not impossible) in outdated, siloed systems. As these regulations continue to evolve, a legacy system may not be equipped to meet them.Ĭompliance regulations like the GDPR, for example, require a company to know (and prove) what customer data they have, where it is, and who is accessing it. Organizations today must abide by strict sets of compliance regulations. If one team maintains a legacy system while the rest of the company upgrades, that one team is isolated from business intelligence and insights being created in integrated systems. In addition to siloing the data they contain, legacy systems keep the departments that use them out of data integration happening in the rest of the organization. This means that each legacy system is its own data silo. Many older systems were never designed to integrate with each other in the first place, and many legacy software solutions are built on frameworks that can’t integrate with newer systems. Data is stuck in silosĭata silos are a byproduct of legacy systems. A legacy system continues to cost a company money for maintenance while never providing new and innovative services. Think of a weak dam with holes that you keep plugging and plugging, yet water keeps seeping through. If the system fails, there’s nowhere to turn. The status quo is maintained, but there’s never a chance for growth with the legacy system.Īt some point, there won’t be any more support for a legacy system and there won’t be any more updates. Maintenance keeps the legacy system running, but at the same time, the company is throwing good money after bad. Maintenance is to expected with any system, but the cost of maintaining a legacy system is extensive. These issues eventually outweigh the convenience of continuing to use an existing legacy system. Sometimes simply planning the migration of data from a legacy system and defining the scope of requirements for a new system are overwhelming.Ī legacy system can cause a myriad of problems, such as exorbitant maintenance costs, data silos that prevent integration between systems, lack of compliance to governmental regulations, and reduced security. There may be little documentation about the system and the original developers have left the company. Difficulty: The legacy software may be built with an obsolete programming language that makes it hard to find personnel with the skills to make the migration.Fear: Change is hard, and moving a whole company -or even a single department - to a new system can inspire some internal resistance.Investment: Although maintaining a legacy system is expensive over time, upgrading to a new system requires an up-front investment, both in dollars and manpower.The reasons are varied as to why a company would continue to use a legacy system. Instead of offering companies the latest capabilities and services - such as cloud computing and better data integration - a legacy system keeps a company in a business rut. A legacy system’s older technology won’t allow it to interact with newer systems.Īs technology advances, most companies find themselves dealing with the issues caused by an existing legacy system. What a legacy system does now for the company is all it will ever do. The system still meets the needs it was originally designed for, but doesn’t allow for growth. What is Shadow IT?
