Sometimes upgrading from one version to the next requires a schema change. In these cases, the CHANGELOG will be explicit. Upgrades MUST be executed WITH the new library (jar) and before the pipeline is executed. Basic pseudocode can be found below as a reference. For actual version upgrade scripts please reference the upgrade scripts linked to your target version in the Changelog.

When a schema upgrade is required between versions, this step cannot be skipped. Overwatch will not allow you to continue on a version that requires a newer schema.

A sample notebook is provided below for reference.
