Other legacy systems might even be hard to update. But new analytics software can do more with the data those sources have been supplying for years, Selvanathan at Waterstone said. Even if the data resides in a closed silo, such as a repository kept used by plant historian software, companies may be able to crunch the numbers again using a platform like Hana.
"The good news is, yes, there's a way to get the data out. The not-so-great news is that it's non-trivial to do that," Selvanathan said. Data extraction, migration and loading takes new infrastructure and system-integration skills that most organizations would have to hire in from outside, he said -- but that's likely to cost a lot less than scrapping what's already there.
