Once the rolling/express upgrade stages complete, it gives the option to choose to Finalize the upgrade, to Finalize Later or to Downgrade. Finalizing later gives you a chance to perform more validation on the cluster. Downgrade moves the cluster version back to the previous version (basically: reverses the upgrade process stages). However once you finalized the upgrade, you cannot downgrade back to the previous version.
