Will there be any issue in my current notebooks and jobs if i upgrade my Databricks run time version from 9.1 LTS to 10.4 LTS

I didn't tried upgrading the version. If I upgrade it then will I be able to change it back to previous version

CodePudding user response：

It's really a very broad question - exact answer depends on the features and libraries/connectors that you're using in your code. You can refer to the Databricks Runtime 10.x migration guide and Spark 3.2.1 migration guide for more information about upgrade.

Usually, the correct way to do is to try to run your job with new runtime, but using the test environment, where your production data won't be affected.
