Update Destination details of email and mail alert notification for recurring schedules

HI,

We have new requirement where the domain of the user email is getting change from @abc123.com to @abc.com. we have 400 recurring schedules in the production which has email as the destination. We also have few 100 schedules which has the notification alert enabled for success and failure status, we also need to change the email address.

I have Java sdk knowledge, but i am struggling to find a right query in place as this seem to be a big task.

please let us know the java sdk script or idea to this.
