Abstract: Some embodiments of the invention provide, for a RAN (radio access network), a method of rapidly upgrading multiple machines distributed across multiple cell sites, each particular machine of the multiple machines executing one or more base station applications. The method downloads a second boot disk for each of the multiple machines at each of the multiple cell sites, the second boot disk including an upgraded version of a first boot disk currently used by each of the multiple machines. For each particular machine, the method (1) powers off the particular machine, (2) creates a copy of data stored by a data disk of the particular machine to preserve data stored currently on the data disk, (3) replaces the first boot disk of the particular machine with the second boot disk that is the upgraded version of the first boot disk, and (4) powers on the particular machine.
