@Will Block​ , a while ago we had some jobs running on non-supported versions.

We did not notice it to be honest, because the jobs kept on working! That was however more than a year ago. The minute we noticed running on a non-supported version, we started migrating.

So chances are that they will keep on running for a while, but without support... I would not take the risk and start migrating/planning ASAP.

@Werner Stinckens​ you can think about the Databricks Runtime as a contract. It does and will change over time. However, we offer Long Term Support versions of the runtime which offer multi-year support. If you have production jobs, I would definitely consider running them on an LTS version. However, as the LTS version phases out of support, please consider migrating to a newer LTS so you can take advantage of the thousands of improvements we release every year.
