extends ProcessManagerMigration<I,P,S,B>

A migration operation that triggers the update of the ProcessManager state according to the logic defined in onBeforeCommit() method, if it is defined.

onBeforeCommit() is designed to contain common logic on setting the calculated state fields. In a normal operational mode, it is executed after a process manager handles some signal and before the respective transaction is committed.

If this calculation logic is changed in the code, end-users may need to update the calculated state of many process managers at once. This migration operation is a straightforward way to invoke the onBeforeCommit() method within a separate transaction and save the changes made by it to the states of process managers.
