Migrate 500+ faulty instances

Assuming I’ve deployed a process definition and over 500 instances are currently utilizing it, what steps can I take to rectify a critical modeling error and migrate all affected instances to an updated version that includes a necessary hotfix?

I already found a community repo that can possibly provide this. Is this the way to go? GitHub - camunda-community-hub/camunda-7-migration: Fluent Java API for Camunda Platform 7 process instance migration

Best regards,

Hi @Th0mas,

process instance migration from one version to another is part of the product. You can use the asynchronous batch migration for the numbers of process instances you have to migrate: Process Instance Migration | docs.camunda.org.

This is the REST Api endpoint to execute the migration: Camunda Platform REST API

Hope this helps, Ingo
