Hi Experts!

We are live in a coexistence model with PeopleSoft 9.2 and we recently had a production to test refresh. Is there an easy way to scramble or remove user emails from the testing environment? Right now I am extracting an hdl file from our test environment and manually manipulating the it to set all the emails to Invalid@mt.gov before loading it. this works but its time intensive. Any better ideas out there?

Thanks in advance!
