Title: METHOD AND ARRANGEMENT FOR MANAGING FUNCTIONALITY CONTROLLING VIRTUAL INFRASTRUCTURE
Abstract:
It is disclosed a controller (500) managing a functionality controlling a virtual infrastructure, and a method performed therein. Also a computer program and a computer program product are disclosed. By temporarily using dual control functions running in separate virtual entities (208; 210), while at most only one is active at a time, upgrading from a first control to a second control function is enabled, without the need to restart a host operating system (222), on which tenant software (234) is running.
