Did you know that Legacy systems often make up a vital part of a company’s IT infrastructure? These systems have generally been in place for many years and are typically used well past the vendor-supported software and hardware lifetime. Legacy systems therefore present a complex strategic problem for IT managers. Indeed, this infrastructure is often used in mission critical processes essential to their businesses.
Legacy systems utilize outmoded programming languages, software and/or hardware that typically are no longer supported by latest ERP software.
These systems are still used by some companies because a change-over may cost them quite a bit and there is a potential risk of business interruption associated with the movement of data and key business processes to more advanced and contemporary technologies.
CTS has seen a number of companies that still heavily rely on decades-old legacy systems. Further complicating the situation, many of these companies have been built through a series of mergers and often must manage a variety of incompatible legacy systems inherited from their predecessor organizations.
In general, legacy systems tend to be given inadequate resources for their proper maintenance, even when an upgrade to contemporary technology is not being contemplated seriously. Companies using Legacy systems should consider working with an external company to maintain and support these systems.
