Change the job Chain Partition

Hi All,

We have 1200 Job Chains in our Redwood Environment and we have the these Job Chains tagged to PROD or either QA partition. Daily i will get 20 requests to change the job partitions from Prod to QA and currently i am changing them manually..Can you please suggest me any script that i can run in the application to change the partition of the jobs automatically with out editing them..

Thanks

Kiran
