Users are usually notified of the software updates when it is available. For desktop software, it will depend on the operating system. In some cases, updates will happen in the background, in others they, will have to be manually installed; for mobile software this is handled via the respective app store notifications. It is recommended that users start the upgrade process when they receive a notification there is an update available. Software upgrades are in-place, meaning that configuration settings are maintained unless there has been an explicit change to that configuration setting. As always with new software, user’s should validate the new software works as expected before using it.
