Legacy systems are computer components that are still in use despite the fact that they are running on old technology, including old school hardware features. They are still used because they form a large, rather bulky yet very important part of the organization in terms of the work they get done, and also their complexity. Furthermore the costs an organization would incur should they attempt to switch to a newer system are exorbitant enough to be discouraging. Therefore replacing a legacy system can turn out to be costly both monetarily and also productively.

With that in mind, organizations not willing to lose these old generation systems choose to try and bring them into the future with the help of current technology – especially with regards to the hardware aspect. If there were a way to emulate the legacy system while using current technology, it would make the process of legacy integration easier. Also, if it were possible to use technology that can allow legacy systems to interact with modern hardware components, then legacy integration would be made practically effortless for the experienced software technician.

However, in spite of how these methods of legacy integration sound simple and inviting, there are several obstacles that typically present themselves. For starters, considering that the creators and designers of the legacy system may not be there anymore to assist with the system, it may be difficult to fully understand the system.

Furthermore, after years of maintenance, upgrading and several changes, the system will not be as it was originally designed, and the documentation if any may not be complete, or may even be out dated. This makes the task of legacy integration even more complicated. It brings to question, which aspects will need to altered or forgone altogether, and at what risk.

Another aspect to keep in mind before performing a legacy integration procedure is to ensure that the data will similarly be integrated. Any loss of data would be unacceptable considering that it cannot be replaced. Especially data that is decades old. Furthermore the destination system of the legacy integration must be able to handle the data. This means that it must be able to freely manipulate all aspects of the data, ensuring continuity in the system.

In addition, the legacy integration procedure must ensure that all parts of the system are still connected. Any “terminal” that interacts with the system, must still be able to attach itself to the system, and be able to complete the original tasks that it used to perform before the legacy integration.

Furthermore, security on the new system must be top notch, security breaches cannot be tolerated. Before the legacy integration, legacy systems may be vulnerable to current hacking methods and thus the new system must be able to protect the system from these issues. There will also be sections of the system that will have to be significantly altered to attain this result.
