I need to deploy a Visual Studio 2008 project in Windows 2000 SP 4 whit .NET 2.0 framekork, but for compatibility reasons i need to know if is posible "downgrade" the rdlc files to Reportviewer 2005.
It seems your question is about local mode reports. VS 2008 RDLC and VS 2005 RDLC files use the same underlying RDL 2005 format, so no downgrade is necessary.
