Update process Definition

[amir_kourani]

Hi,
Is there a way  to udate process Definition and all its instances if so , what will happen to the current task of the running instance?
if there is a documentation to this , please specify the link.
Thank you.

Hi,

Updating process instances to a new process definition version is difficult to implement fully generic.
We have a ProcessInstanceMigrationTest unit test and a SetProcessDefinitionVersionCmd command class that provide some help for this.
But what's really important is that the active activity instance is also present in the new process definition. If that's the case, then the migration could work.

Best regards,
