 Hi,

   Can some one guide me how to deploy SSRS 2008 reports to SharePoint 2013 by giving the exact steps from where to begin. We have all our reports deployed in SharePoint 2010.Need to migrate those reports to Sharepoint 2013 instance. I also want to know how and where exactly we modify the connection strings to manage the data sources for the reports . Since I am very new to this field I am not able to properly understand other sites i have gone through . I have gone through the prerequisites also.Kindly help me by providing step by step method.

Thanks,
