So... what is the solution? There are times where a legacy technology has limitations that ultimately prevent progress and create maintenance nightmares. A good example is some of the older database technologies where a 1TB database machine could cost 100k (example: Sybase). You could try to maintain a series of expensive databases, but between replication backups, dev boxes, team of DBAs etc suddenly your costs to keep the old technology are really high. And if these are databases storing expensive financial data, well, maybe the risk of hitting your 1TB limit is an expensive risk to have on your plate. And it might take 10MM to migrate to a new technology, but in this case it would probably be worth a switch. When technology is a commodity, and working poorly is still working, then maybe it's hard to justify a switch. But if your old technology starts to limit your performance and introduce risks or problems that detract from your competitive advantage, then you might not have a choice.
