When code is born of old: Architectural obsolescence within the development life cycle - Story
April 11, 2011
Portability is not just relevant to software migration during the lifetime of a product. In complex military projects where the development cycle can easily take up to 10 years, software might have to be ported to new architectures two or three times. Unless specific steps are taken to ensure platform portability, such migration accelerates project overage, extending work schedules right through testing and verification. The ideal would be to anticipate such an occurrence and plan to minimize its impact, but the right software test tools can smooth the way even when porting legacy code written without such foresight.

It can be a real nightmare when a customer wants a new solution based upon legacy software for which the original developers left no clear indication of design criteria. But finding the proper analysis methodologies and tool suites can help developers get a good night's rest.

Legacy code in the security-critical age - Story
July 08, 2008
The cost and convenience advantages of legacy code reuse can be diminished or complicated when security and safety-critical risks are considered. If the legacy code is proven to be functionally correct and operationally viable, its acceptance is based on an assumption of what is expected to happen. However, it is the unexpected that typically causes faults, and structural testing provides a means of mitigating the unexpected.
