How to changes or update local server connection in Maintenance plan job Two days back our client changed one of our Dev Server name 

After Server Renamed, All my maintenance jobs and other jobs are failing because server name mismatch.

We are using sql server 2012 version and server 2008 OS

So today morning i renamed my Sql server 2012 name to updated given name and made table, procedures updates

I tried to update Local server connection in maintenance job but it is uneditable.
Then i added new server connection,still no use i am getting below error, while executing jobs.

After i tried with target page in jobs property option, there also only target server is selected and multiple target server is disable.

Error below

Help me out in this guys, Thanks in advance
Maintenance plans make use of SSIS packages that are stored in MSDB. These packages use connection strings, which are not changed after a server rename.

Use the script (reproduced below) posted by NancySon in the comments of How to: Rename a Computer that Hosts a Stand-Alone Instance of SQL Server to get some inspiration on how to change these connection strings. Or recreate the maintenance plans.


  Maintenance plans don't get their connections changed to the new server name and so they may break. After a rename you may find that you cannot delete or rename the existing maintenance plans, so either delete them before renaming the server and recreate them afterwards or run the following script to fix them:

   use msdb

   DECLARE @oldservername as varchar(max)
    SET @oldservername='&lt;server name&gt;\&lt;instance name&gt;'

   -- set the new server name to the current server name

   declare @newservername as varchar(max)
    set @newservername=@@servername

   declare @xml as varchar(max)
    declare @packagedata as varbinary(max)
    -- get all the plans that have the old server name in their connection string
    DECLARE PlansToFix Cursor
    FOR
    SELECT    id
    FROM         sysssispackages
    WHERE     (CAST(CAST(packagedata AS varbinary(MAX)) AS varchar(MAX)) LIKE '%server=''' + @oldservername + '%')

   OPEN PlansToFix


   declare @planid uniqueidentifier
    fetch next from PlansToFix into @planid

   while (@@fetch_status&lt;&gt;-1)  -- for each plan

   begin
    if (@@fetch_status&lt;&gt;-2)
    begin
    select @xml=cast(cast(packagedata as varbinary(max)) as varchar(max)) from sysssispackages where id= @planid  -- get the plan's xml converted to an xml string

   declare @planname varchar(max)
    select @planname=[name] from  sysssispackages where id= @planid  -- get the plan name
    print 'Changing ' + @planname + ' server from ' + @oldservername + ' to ' + @newservername  -- print out what change is happening

   set @xml=replace(@xml,'server=''' + @oldservername + '''','server=''' + @newservername +'''')  -- replace the old server name with the new server name in the connection string
    select @packagedata=cast(@xml as varbinary(max))  -- convert the xml back to binary
    UPDATE    sysssispackages SET packagedata = @packagedata WHERE (id= @planid)  -- update the plan

   end
    fetch next from PlansToFix into @planid  -- get the next plan

   end

   close PlansToFix
    deallocate PlansToFix






  ----- This will also handle the packages that have a tag such as 
    ----- &lt;DTS:Property DTS:Name="ConnectionString"&gt;Data Source=servername;Integrated Security=SSPI;Connect Timeout=30;&lt;/DTS:Property&gt;



   DECLARE @oldservername as varchar(max)
    SET @oldservername='&lt;server name&gt;\&lt;instance name&gt;'-- set the new server name to the current server name
    declare @newservername as varchar(max)
    set @newservername = @@servername
    declare @xml as varchar(max)
    declare @packagedata as varbinary(max)-- get all the plans that have the old server name in their connection string
    DECLARE PlansToFix Cursor FOR 
    SELECT id
