1. A method implemented by one or more processors of a computer executing instructions of an upgrade management system stored in memory on the computer, the method comprising: Detecting, by the upgrade management system, an update for an access manager executing on a computer system, wherein the update is for a first version of the access manager to a second version of the access manager; based on detecting the update to the first version of the access manager, automatically updating, by the upgrade management system executing on the computer system, the first version of the access manager on the computer system to execute the second version of the access manager on the computer system, wherein the updating includes: retrieving, by the upgrade management system, the configuration of the first version of an access manager executing on the computer system to protect access to one or more resources, wherein the configuration includes one or more functional settings of the first version of the access manager, and wherein the configuration includes one or more policy parameters of the first version of the access manager that defines authentication for accessing the one or more resources; extracting, by the upgrade management system, the one or more policy parameters from within the configuration of the first version of the access manager; extracting, by the upgrade management system, the one or more functional settings from within the configuration of the first version of the access manager; generating, by the upgrade management system, a configuration of the second version of the access manager to protect access to the one or more resources, wherein generating the configuration of the second version includes: modifying the one or more policy parameters for adjustment from the first version of the access manager to the second version of the access manager; and modifying the one or more functional settings of the first version of the access manager for adjustment from the first version of the access manager to the second version of the access manager; and modifying, by the upgrade management system, based on the generated configuration of the second version of the access manager, a control flow for executing the access manager, wherein the control flow is modified from the first version of the access manager to the second version of the access manager for execution on the computer system; and initiating execution of the second version of the access manager on the computer system using the modified control flow from the first version of the access manager to the second version of the access manager.
