Let me tell you an anecdote. A while back I was discussing immortality with a friend. He’s about my age, close to the same age as COBOL, so lets say his vintage would now be legacy. He’s healthy, functions well, can still process information, do the chores and care for the household. I asked him if he could have a new set of organs transplanted today, specifically the heart, which could extend his useful life for another 20 years would he consider it. He quickly said no, why would I risk it now while I ‘m still healthy. That’s the legacy dilemma.
The heart of a corporation is essential to supporting it’s strategies and actions and therefore it’s outcomes. Why replace it while it still works. It’s slower, it’s less responsive, and with each day it heads towards certain failure. Yet today it works and the fear of replacing it is greater than the obvious. Unfortunately, just like my friend, who wouldn’t consider a transplant until his heart had stopped, many businesses wait until a merger, piece of legislation, system failure, loss of business or death of the corporation. There are plenty of these candidates, and the numbers are growing exponentially.
Legacy Modernization is for the feint hearted, that’s the dilemma. It is also the most practical solution to organizational immortality.
What about the healthy legacy sites, until a customer is against the ropes, they postpone modernizing their systems. They understand it, and in fact they spend a lot of money discussing it, but in the end they do nothing.
So what is the next best thing? In the case of a healthy legacy human, it would include proper diagnostics and expert advice on a heart smart program of diet and fitness and medication. Do nothing and you can hope that expensive and painful alternatives; bypass surgery, stents, angioplasty and pacemakers, or application wrapping, workarounds, jobal, and more hardware will keep you alive.
So at a minimum legacy environments should document and fully understand their current state from a business, application and data level and plan out a legacy migration intelligently. Smart modernization, for a smarter planet!
