Why do most migrations fail?

When I first started working as a software engineer at a financial services company, my first assignment wasn’t glamorous: I was asked to migrate a service from a legacy framework to a newer, more modern application framework. It was interesting as a new joiner in that it allowed me to dig into pieces of a large codebase that I didn’t understand well, but I quickly learned that I’d need to change lots of code and do so in a repetitive manner with only slight variance from module to module. It was the kind of mind-numbing work that lent itself to automation, and I was able to speed up my efforts by writing a series of refactoring scripts.
