A common challenge and administrator and developer face is when they have to migrate content between SQL Server Reporting Server. This is because SQL Server Reporting Services doesn’t include a feature for migrating content items from one reporting services to another report server.
There are two ways to overcome the challenge:
1. Create RSS scripts that are used by rs.exe to migrate the content between reports servers of the same mode or different modes.
2. Run Reporting Services Migration Tool to migrate the content from Native mode report server to a SharePoint mode report server.
This whitepaper discuss the reporting services migration tool and several aspects of method of migration.
