We have migrated from SSRS 2012 to SSRS 2016, and moved it to a new domain.
Using below code, we are able to list all datasources and their connection strings. How can we change the connection strings of nearly 700 reports using PowerShell or T-SQL? (so that the point to new data warehouse server)
WITH XMLNAMESPACES -- XML namespace def must be the first in with clause.
(DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2006/03/reportdatasource'
,'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner'
AS rd)
,SDS AS
(SELECT SDS.name AS SharedDsName
,SDS.[Path]
,CONVERT(xml, CONVERT(varbinary(max), content)) AS DEF
FROM dbo.[Catalog] AS SDS
WHERE SDS.Type = 5) -- 5 = Shared Datasource
SELECT CON.[Path]
,CON.SharedDsName
,CON.ConnString
FROM
(SELECT SDS.[Path]
,SDS.SharedDsName
,DSN.value('ConnectString[1]', 'varchar(150)') AS ConnString
FROM SDS
CROSS APPLY
SDS.DEF.nodes('/DataSourceDefinition') AS R(DSN)
) AS CON
-- Optional filter:
-- WHERE CON.ConnString LIKE '%Initial Catalog%=%TFS%'
ORDER BY CON.[Path]
,CON.SharedDsName;

You can use the
replace value of
XML DML command to modify the value stored in the connection string. I have put together an example below for you as a guide but please note that it is untested as I do not have access to a report server at the moment, it should at least point you in the correct direction:More information regarding the
replace value of
command can be found at Microsoft Docs.
