Abstract: The present disclosure discloses a service migration method including: sending, by a VNFM module, a virtual machine VM request command to a first VIM module, where the first VIM module manages a first host on which post-upgrade new-version software is configured; receiving, by the VNFM module, a VM request response from the first VIM module, where the VM request response includes information about a first VM that the first VIM module requests on the first host, and virtual machine own data that can run on the first host and that is configured by the first VIM module is configured on the first VM; and sending, by the VNFM module, a service migration command to a virtualized network function VNF module, where the service migration command is used to instruct the VNF module to migrate a running service on a second VM to the first VM.
