Legacy system: An outdated technology, hardware, computer system, or application program that is still used within an organization due to its ongoing relevance or data conversion challenges.

Strategies for Integration during Mergers

Strategies for merging IT systems include maintaining both systems, replacing them, merging the best aspects of each, or choosing one over the other.
