The Classic architecture is a term that describes the components carried forward from the 5.0 version of Microsoft Dynamics NAV.
Microsoft Dynamics NAV 2009 customers can opt to migrate to the new architecture immediately, gradually, or not at all. Microsoft has designed Dynamics NAV 2009 so that the Classic and RoleTailored architectures, and their respective components, can co-exist without conflict within a single organization.
Within the Classic architecture, the Classic client connects to either a Microsoft SQL Server database server or to a Classic database server (the proprietary NAV database server). In the RoleTailored architecture, SQL Server is the only database server.
The Classic client is the one Classic component that remains essential for all Microsoft Dynamics NAV 2009 installations, as a tool for development and administration tasks. For example, you must use the Classic client to upload your Microsoft Dynamics NAV 2009 license file.
