- All Implemented Interfaces:
Serializable
,Command<Void>
Command
that changes the process definition version of an existing
process instance.
Warning: This command will NOT perform any migration magic and simply set the
process definition version in the database, assuming that the user knows,
what he or she is doing.
This is only useful for simple migrations. The new process definition MUST
have the exact same activity id to make it still run.
Furthermore, activities referenced by sub-executions and jobs that belong to
the process instance MUST exist in the new process definition version.
The command will fail, if there is already a ProcessInstance
or
HistoricProcessInstance
using the new process definition version and
the same business key as the ProcessInstance
that is to be migrated.
If the process instance is not currently waiting but actively running, then
this would be a case for optimistic locking, meaning either the version
update or the "real work" wins, i.e., this is a race condition.- Author:
