Context:

Due to the schema change implemented with OPT-4462, we temporarily altered the UpgradeSchemaIT to use the old fieldname "events" instead of the new name "flownodeInstances" when asserting old vs new data counts. Once we've reached the next Optimize version where "old" indices also have the "flownodeInstances" field, we can readjust this to refer to the field as "flownodeInstances" and not "events".
Note that we can expect this test to fail once we've reached the next Optimize version.

AT:

• UpgradeSchemaIT no longer refers to old "events" field in processInstances
