The NZ Transport Agency avoided a $70 million rebuild of its driver and vehicle registration system via a carefully-planned migration that moved ageing mainframe apps onto a modern Windows server environment. Its experience provides 10 useful lessons in how to manage large-scale app migrations while minimising risks and costs.
Mainframes are far from dead, but many businesses periodically revisit their mainframe usage to determine if shifting to a more modern platform makes sense.
