Method Detail

migrate

public MigrationResult migrate(EngineListeners engineListeners,
                               MigrationListeners migrationListeners)

Assumes a 1:1 mapping of plan items / discretionary items to plan item definitions. This is not a CMMN requirement but enforced by VIS.

The three main steps of the algorithm: <ul> <li>Match plan item model IDs in use against new model. <li>Update IDs of stored plan item state with the new IDs.</li> <li>Ensure stage hierarchy consistency, introducing new stages where necessary.</li> </ul>
