Legacy systems integration

Definition

Legacy systems integration refers to the process of connecting and allowing new applications or systems to interact with outdated or existing technology that an organization still relies on. This integration is crucial for ensuring that businesses can leverage their existing investments while adopting newer, more efficient technologies. It often involves overcoming compatibility issues, data migration challenges, and maintaining functionality without disrupting current operations.

5 Must Know Facts For Your Next Test

1. Legacy systems are often built on outdated technology but may still perform critical functions for an organization, making their integration essential.
2. Integrating legacy systems can lead to improved efficiency by allowing new applications to utilize existing data and processes.
3. Common challenges of legacy systems integration include dealing with proprietary formats, lack of documentation, and resistance to change from users accustomed to the old systems.
4. Successful legacy systems integration often requires a phased approach to minimize disruption while gradually transitioning to new technologies.
5. Organizations must carefully plan for data security and compliance during legacy systems integration, as older systems may not meet current standards.
