FromSQL Server Data Tools (SSDT), you can publish either all the reports and shared data sources in a Report Server project to a report server by deploying the project, or you can publish a single report. Before you can publish a report you must specify the URL of the target report server. For more information, see Set Deployment Properties (Reporting Services).
You can use the SQL Server 2008 R2 version of SQL Server Data Tools (SSDT) to open, modify, preview, save, and publish both SQL Server 2005 Reporting Services (SSRS) and SQL Server 2008 Reporting Services (SSRS) reports. For more information, see Deployment and Version Support in SQL Server Data Tools (SSRS).
