1. A system comprising:
one or more processors; and
a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to:
generate an upgrade token;
record the upgrade token;
set an authentication-authorization service to an offline mode, the authentication-authorization service being available to grant and validate access tokens when in an online mode and being unavailable to grant and validate the access tokens when in the offline mode;
determine a match between a received upgrade token and the recorded upgrade token in order to prevent unauthorized access of an upgrade implementation module while the authentication-authorization service is offline; and
authorize implementation of an upgrade package associated with the upgrade token by the upgrade implementation module while the authentication-authorization service is in the offline mode on a basis of the match.
