Abstract
A method includes receiving a request to install a software release, where the software release is to be installed on a first device and/or a second device. The method also includes initiating installation of the software release on the second device and determining whether or not a user wishes to continue with the installation of the software release. The method further includes initiating installation of the software release on the first device if the user wishes to continue. In addition, the method includes restoring a second software release on the second device if the user does not wish to continue. The first and second devices may represent redundant devices, such as a redundant set of controllers in a process control system or a redundant set of I/O modules that facilitate communication between one or more controllers and one or more process elements in the process control system.
