Simulating end-to-end upgrade process in production environment
System and methods for simulating an end-to-end upgrade process are provided. The method may include collecting, by an upgrade simulator, a system inventory from a production system. The system inventory includes the production system's hardware configuration. The method may include, in response to a determination that the system inventory is compatible with an upgrade software, configuring, by the upgrade simulator, a simulated system having a downsized hardware configuration compared to the production system's hardware configuration. The method may further include upgrading, by the upgrade simulator, the simulated system using the upgrade software, and evaluating, by the upgrade simulator, the simulated system operating with the upgrade software.

before the upgrading of the simulated system using the upgrade software, populating, by the upgrade simulator, the simulated system with a subset of the production system's user data.
8. The method of claim 1 , further comprising:
in response to a determination that the simulated system with the upgrade software is performing normally, upgrading, by the upgrade simulator, the production system with the upgrade software.
9. A non-transitory, computer-readable storage medium, containing a set of instructions which, when executed by a processor, cause the processor to perform a method for simulating an end-to-end upgrade process, the method comprising:
collecting, by an upgrade simulator executing on a management server, a system inventory from a computer system, wherein the system inventory includes the computer system's hardware configuration and software configuration;
determining that the system inventory is compatible with an upgrade software by comparing the system's hardware and software configurations to a hardware compatibility matrix and a software compatibility matrix, respectively, wherein the matrices are stored at the management server;
configuring, by the upgrade simulator, a simulated system having a downsized configuration having a minimum simulated hardware and software configuration that can represent the computer system;
upgrading, by the upgrade simulator, the simulated system using the upgrade software; and
determining, by the upgrade simulator, whether the computer system can be upgraded with the upgrade software by evaluating the simulated system operating with the upgrade software.
10. The non-transitory, computer-readable storage medium of claim 9 , wherein the determination that the system inventory is compatible with the upgrade software comprising:
stopping the upgrade process based on the determination that the simulated system operating with the upgrade software is behaving abnormally.
11. The non-transitory, computer-readable storage medium of claim 9 , wherein the system inventory further includes the production system's customization configuration, the method further comprising:
before the upgrading of the simulated system using the upgrade software, applying, by the upgrade simulator, the computer system's customization configuration to the simulated system.
12. The non-transitory, computer-readable storage medium of claim 9 , wherein the system inventory further includes the computer system's user data, the method further comprising:
before the upgrading of the simulated system using the upgrade software, populating, by the upgrade simulator, the simulated system with a subset of the computer system's user data.
