Following query is handful in case of migrating reports to different Report Server or when shared data sources should be changed, renamed or deleted.  Query takes some time to be executed because of XML parsing.

    SELECT [ItemID], [Name], [Type],
         [Xml] = TRY_CONVERT(XML, CONVERT(VARBINARY(MAX), [Content]))
