Abstract
A non-disruptive upgrade (NDU) technique involves installing and activating a first copy of a new version of an application in a temporary directory to (i) obtain control from an original version of the application while the original version is installed in an application directory and (ii) shut down the original version. The technique further involves, after the first copy of the new version obtains control from the original version and the original version is shut down, installing and activating a second copy of the new version of the application in the application directory to (i) obtain control from the first copy of the new version while the first copy of the new version is installed in the temporary directory and (ii) shut down the first copy of the new version. Such operation maintains the continuity of work at each phase of the NDU technique.
