The solution to long-term archiving for decommissioned systems.
Computer systems have a lifecycle. They’re created, used and, eventually, decommissioned – the system’s “death”. Some are short-lived, such as a system fulfilling a proof of concept or another temporary requirement.
Others remain in use for decades, often for the prosaic reason that the system works and the risk or cost
of replacement is unjustified. The US Department of Defence’s MOCAS contract-management system was launched in the 1950s and is still operational.
