The retirement app , also called decommissioning app and the sunsetting app , is the practice of shutting down excessive or outdated business applications while retaining access to historical data. Legacy applications are often maintained only to provide sparse or sporadic data access to the application database for regulatory or business purposes. With some organizations spending more than 75% of their application software budget on ongoing maintenance, retirement applications can provide significant cost savings.
Retirement application actions typically involve migrating data from legacy application databases to other data repositories or archival storage that can be accessed independently using industry standard reporting or business intelligence tools. Retirement applications enable IT departments within the company to reduce the software, hardware, and resources needed to manage legacy data.
