The LM Program Update is published quarterly and provides information on LM sites, activities, and events. Virtualization technology is a recent innovation allowing legacy systems to continue to operate on modern hardware by running older operating systems and browsers on a software system that emulates legacy hardware. For example, Operating systems with "legacy support" can detect and use older hardware. [11] Even before the Shuttle was scheduled to be retired in 2010, NASA found it advantageous to keep using many pieces of 1970s technology rather than to upgrade those systems and recertify the new components. In the modern business computing environment, n-tier, or 3-tier architectures are more difficult to place into legacy mode as they include many components making up a single system. [2], Where it is impossible to replace legacy systems through the practice of application retirement, it is still possible to enhance (or "re-face") them.
