Patent number: 9396004Abstract: An embodiment of a system and method of managing a configuration of a virtual machine. An embodiment may include analyzing a configuration of a first computing system to identify a native configuration related to a first virtual machine and analyzing a second computing system to determine whether or not the native configuration should be used to configure the second computing system. If the native configuration should be used to configure the second virtual machine then an embodiment may include using the native configuration information to establish a second virtual machine on the second computing system, and if the native configuration should not be used to configure the second virtual machine then using the native configuration information to create intermediate configuration information and using the intermediate configuration information to establish a second virtual machine on the second computing system.Type: GrantFiled: April 21, 2015Date of Patent: July 19, 2016Assignee: ZERTO LTD.Inventors: Ofer Bester, Doron Mayer, Omri Shefi, Yoav Morag, Yair Manor
