legacy technology
Inherited outdated infrastructure
Legacy technology refers to older systems, software, or hardware still in use despite being outdated or superseded by newer alternatives.
Organizations often maintain legacy systems because replacement is costly or risky, or because the technology still performs critical functions: The bank's legacy mainframe handles millions of transactions daily.
The term carries slight disparagement—functional but antiquated.
