In this blog series we’ll be experimenting with the most interesting blends of data and tools. Whether it’s mixing traditional sources with modern data lakes, open-source devops on the cloud with protected internal legacy tools, SQL with noSQL, web-wisdom-of-the-crowd with in-house handwritten notes, or IoT sensor data with idle chatting, we’re curious to find out: will they blend? Want to find out what happens when IBM Watson meets Google News, Hadoop Hive meets Excel, R meets Python, or MS Word meets MongoDB?

Today: KNIME Meets KNIME - Will They Blend?
Author: Phil Winters
Imagine you have been happily getting and using a new version of KNIME Analytics Platform with all of its additional features and functionality twice a year for many, many years.
But one day, you are required by your organization to pull out something from your distant KNIME past – something that at the time was very, very important and that needs to work EXACTLY the same way today.
But you’ve heard all the horror stories of other data science tools and platforms that have changed so fundamentally between versions (sometimes yearly) that a time-consuming migration (or even a rewrite) is required to get the old code to work. And of course, there is no guarantee from these vendors of backward compatibility nor that the results will be the same even when you do get it to work again. But what about KNIME? Will the old easily blend with the new? That is our challenge today!
Topic. Backward compatibility of KNIME Workflows
Challenge. Reuse the oldest KNIME workflow available in today’s current KNIME version
