You CANNOT switch from one mode to the other. You will have to reinstall to make life easier. This is what we had to do to correct an installation (re-install as integrated mode).
You can start by using SharePoint 2010, where you can configure a report server as element of a SharePoint development. SharePoint Products' Reporting Services Add-in and the SQL Server helps in the integration, which in turn offers benefits in document access, storage, and security. Once the configuration is complete, a session with the associated Report Server will get established when a report in SharePoint is opened, which in turn will help you to retrieve and process the data as results will get displayed in SharePoint's Report Viewer Web Part.
