Changing ownership of Reports in SRS

One of our developers left the company and we had to reactivate his Windows Account so the Reports he created in SQL Reporting Services wouldn't fail; is there a way to programmatically change ownership of Reports; it would be very cumbersome to have to republish every one of them manually.
Thanks.

No 100% sure, but i think one of the fields in the Catalog table of the Report Server database holds the owner info. You could possibly write some SQL to update this? Hope that helps!
