Indeed - banks often struggle replacing or integrating new finance/customer systems with their massive (often Cobol) legacy systems...but we are not talking complex financial records in ancient legacy systems here.As someone who has spent the last 20 years in IT I can assure you that it is more common than you may think that there are failings on new mission critical systems. Banks have done it and it’s very common in the public sector and it’s normally because some “expert” convinces management that “it will be fine”.
Maybe 'management' would be less accepting of 'expert' advice if they knew that the system had huge public visibility and that it was critical to the health of the nation (literally).
