Native to SharePoint Migration (SSRS)
You cannot upgrade or convert from one Reporting Services server mode to another. For example, you cannot upgrade or convert a Native mode report server to SharePoint mode. You cannot copy the report server databases between modes because they use different database schemas. You can migrate the content from one report server to another. The tools you use depend on the type of report server mode that is configured for the source and destination servers.
