Abstract
A system and method for exchanging an old software version for a new version within a telecommunications switch without a system restart. The switch includes memory, a software loading subsystem, a database management subsystem, and a program exchange subsystem. The new software version is exchanged for the old software version by loading the new software version into the memory of the switch using the software loading subsystem. The new software version is then registered in the program exchange subsystem using the database management subsystem. The old software version is passivated, and the new software version is activated using the program exchange subsystem, thereby, exchanging the old software version for the new software version.
