Software update control device, software update control method, and recording medium having software update control program stored thereon

A software update control method comprising, by an information processing device:

• performing control in such a way that, when a second information processing system processes original output information output by first information processing resources included in a first information processing system executing software before update, second information processing resources included in the second information processing system execute the software being updated;
• verifying a trial operation in which the second information processing system processes information output by the second information processing resources executing the updated software;
• performing control in such a way that, when a verification result with respect to the trial operation indicates being normal, a state of outputting the original output information is transferred from the first information processing resources to third information processing resources included in the second information processing system, and the second information processing system is able to process the original output information output by the third information processing resources;
• performing control in such a way that, after entering a state in which the second information processing system is able to process the original output information output from the third information processing resources, the first information processing resources output updated output information by executing the updated software;
• and
• switching processing target information being a processing target of the second information processing system, from the original output information output by the first or third information processing resources, to the updated output information output by the first or second information processing resources.

A non-transitory computer readable recording medium storing a software update control program causing a computer to execute:

• first execution control processing of performing control in such a way that, when a second information processing system processes original output information output by first information processing resources included in a first information processing system executing software before update, second information processing resources included in the second information processing system execute the software being updated;
• verification processing of verifying a trial operation in which the second information processing system processes information output by the second information processing resources executing the updated software;
• transfer control processing of performing control in such a way that, when a verification result by the verification processing with respect to the trial operation indicates being normal, a state of outputting the original output information is transferred from the first information processing resources to third information processing resources included in the second information processing system, and the second information processing system is able to process the original output information output by the third information processing resources;
• second execution control processing of performing control in such a way that, after processing by the transfer control processing is performed, the first information processing resources output updated output information by executing the updated software;
• and
• switching processing of switching processing target information being a processing target of the second information processing system, from the original output information output by the first or third information processing resources, to the updated output information output by the first or second information processing resources.
