In technology contexts, legacy refers to older computer systems, software, or equipment still in use despite being outdated. Municipal governments often rely on legacy systems for critical functions like property tax management, utility billing, or permit tracking. These systems may work reliably but lack modern features, integration capabilities, or security updates. Replacing legacy systems is expensive, risky, and time-consuming, requiring data migration and staff retraining. However, maintaining legacy systems also carries risks including difficulty finding technical support, compatibility problems with newer technology, and security vulnerabilities. Municipal IT departments must carefully balance upgrade costs against operational needs.
