Hello, I have just started learning about Temporal and am trying to update the CronSchedule for a previously created workflow.  
However, I cannot find any documentation on how to do this.  
I noticed the updateWorkflowExecution method, but when I tried it, I received an error message saying ‘PERMISSION\_DENIED: UpdateWorkflowExecution operation is disabled on this namespace.’  
Is there any way for me to enable the UpdateWorkflowExecution feature?

Hello,

> ‘PERMISSION\_DENIED: UpdateWorkflowExecution operation is disabled on this namespace.’

for this error, I think you need to set `frontend.enableUpdateWorkflowExecution=true `in your dynamic config, see this example

> am trying to update the CronSchedule for a previously created workflow.

I am not sure if I get this question and how it is related to UpdateWorkflowExecution, are you trying to update the [What is a Temporal Workflow? | Temporal Documentation](https://docs.temporal.io/workflows#spec) in the Schedule?

Thank you very much for your feedback.  
I would like to update the CronSchedule of a previously created workflow, but I am not sure if I can do it with UpdateWorkflowExecution.  
Up until now, the solution that I have implemented is to delete the old workflow and create a new one with the new CronSchedule.  
However, if there is a better solution available, please let me know.

@nnv_saka

If you refer to cronSchedule [temporal-cron-job](https://docs.temporal.io/workflows?&_ga=2.125076364.762961638.1687709919-167080156.1680123165#temporal-cron-job) , they can not be updated, you can use this approach instead [samples-java/core/src/main/java/io/temporal/samples/updatabletimer/README.md at main · temporalio/samples-java · GitHub](https://github.com/temporalio/samples-java/blob/main/core/src/main/java/io/temporal/samples/updatabletimer/README.md)

or if you can, better use the new schedule feature that will allow you to update the schedule as this example demonstrate

> <https://github.com/temporalio/samples-java/blob/307a2df3e5adc269fb21d8a7e8afdd001d9ef72d/core/src/main/java/io/temporal/samples/hello/HelloSchedules.java#L224>

Let me know if this example helps,

Antonio

@antonio.perez on another note is it recommended to use @UpdateMethod in production? We see it marked as @Experimental in the latest java SDK.

what if we just want to create a simple CRON schedule? If I follow this [How do I convert my Cron into a Schedule? | Temporal Technologies](https://temporal.io/blog/how-do-i-convert-my-cron-into-a-schedule) How do i make sure that on application restart a new schedule isnt created?
