Abstract: An apparatus and method for managing application context is provided. A first one of a plurality of terminals, each including at least one application, collects and transmits context information of the application to a migration server so that it is stored and managed in the migration server. The migration server transmits the stored and managed context information to a second terminal corresponding to the first terminal in response to a request of the second terminal. The second terminal restores context based on the context information received from the migration server. This can reproduce the same application and desktop environments as those previously set to be suitable for each work situation, thereby increasing user convenience.
