Hi @James Adkins
You can try to use the code below. Be sure to try it in your development environment first before doing in production and make a backup in production before executing the code.
For guidance, read on this post also.

USE ReportServer; -- Replace ReportServer with your SSRS database name
UPDATE dbo.Catalog
SET OwnerID = (SELECT UserID FROM dbo.Users WHERE UserName = '<newOwner>')
WHERE OwnerID = (SELECT UserID FROM dbo.Users WHERE UserName = '<currentOwner>')
AND Type = 2; -- Type = 2 specifies that the item is a report
