Class MigrateProcessInstanceCmd
java.lang.Object
org.camunda.bpm.engine.impl.migration.AbstractMigrationCmd
org.camunda.bpm.engine.impl.migration.MigrateProcessInstanceCmd
How migration works:
- Validate migration instructions.
- Delete activity instances that are not going to be migrated, invoking execution listeners and io mappings. This is performed in a bottom-up fashion in the activity instance tree and ensures that the "upstream" tree is always consistent with respect to the old process definition.
- Migrate and create activity instances. Creation invokes execution listeners and io mappings. This is performed in a top-down fashion in the activity instance tree and ensures that the "upstream" tree is always consistent with respect to the new process definition.
