You might wonder what happens with business applications during a complex mainframe migration project. Will there be a significant code freeze needed?

This is achievable when two conditions are met:
Let’s have a look at the automation first: the code transformation is 100% automated, as well as the testing: both versions of the code – the original and the transformed one – are compared automatically. The differences are analyzed and based on that, the tools are improved. A new round of transformation and testing is undertaken, again and again, until the result is correct 100%.
