Update the data source of multiple SharePoint 2013 report view webparts at one time?

Update the data source of multiple SharePoint 2013 report view webparts at
one time?

I have 14 SharePoint 2013 site collections with hundreds of sub sites.
Each of the sites has three reports that display using the report viewer
web part. Most of these report view web parts point to our old SQL 2005
server. Is there a way to write a PowerShell script to update these
addresses at once to reflect the current server?
