A resource migration method and apparatus are provided, so that a terminal device can change, according to a specific condition, an SFE serving the terminal device. The method includes: determining, by a terminal device, that a service function entity SFE serving the terminal device needs to be changed to a first SFE; acquiring information about a location of a resource/subresource corresponding to the terminal device in a second SFE, where the second SFE saves the resource/subresource corresponding to the terminal device; and sending, to the first SFE, a first identifier and the information about the location in the second SFE, where the first identifier is used to indicate that the terminal device needs to change the SFE serving the terminal device, so that the first SFE transfers, after receiving the first identifier, the resource/subresource corresponding to the terminal device from the second SFE to the first SFE.
