The device management system comprises an entry server, a first server, a second server, and an electronic device bound with the first server. The device management method comprises: sending, by the entry server, a server-switching instruction corresponding to the electronic device to the first server, such that the first server sends a binding termination instruction to the electronic device; sending, by the electronic device, an address-requesting instruction corresponding to the second server to the entry server, such that the entry server sends an address of the second server to the electronic device; and sending, by the electronic device, a registration information instruction to the second server to execute binding, and exchanging data information with the second server. In this way, data only needs to be modified on the entry server, and the electronic device can automatically find the correct server. ## Claims ### Claim 1 A device management system, comprising: an entry server; a first server, coupled to the entry server; a second server, coupled to the entry server; and an electronic device, bound with the first server; wherein the device management system executes a device management method, and the device management method comprises: sending, by the entry server, a server-switching instruction corresponding to the electronic device to the first server, so that the first server sends a binding termination instruction to the electronic device; sending, by the electronic device, an address-requesting instruction corresponding to the electronic device to the entry server, so that the entry server sends an address of the second server to the electronic device; and sending, by the electronic device, a registration information instruction to the second server to execute binding, and exchanging data information with the second server. ### Claim 2 (depends on 1) The device management system according to claim 1, wherein the first server and the second server are Internet of Things servers, and the electronic device is an Internet of Things device. ### Claim 3 (depends on 1) The device management system according to claim 1, wherein the device management method further comprises: verifying the binding termination instruction by the electronic device using a public key of the first server to determine whether to terminate binding. ### Claim 4 (depends on 1) The device management system according to claim 1, wherein the sending, by the electronic device, the registration information instruction to the second server to execute binding comprises: receiving, by the electronic device, a registration-permitting instruction and a public key from the second server. ### Claim 5 (depends on 4) The device management system according to claim 4, wherein the exchanging of the data information between the electronic device and the second server comprises: verifying the data information by the second server using the public key of the electronic device in the registration information instruction to determine whether to receive the data information. ### Claim 6 A device management method suitable for a device management system, wherein the device management system comprises an entry server, a first server, a second server, and an electronic device, the electronic device and the first server are bound together, and the device management method comprises: sending, by the entry server, a server-switching instruction corresponding to the electronic device to the first server, so that the first server sends a binding termination instruction to the electronic device; sending, by the electronic device, an address-requesting instruction corresponding to the electronic device to the entry server, so that the entry server sends an address of the second server to the electronic device; and sending, by the electronic device, a registration information instruction to the second server to execute binding, and exchanging data information with the second server. ### Claim 7 (depends on 6) The device management method according to claim 6, wherein the first server and the second server are Internet of Things servers, and the electronic device is an Internet of Things device. ### Claim 8 (depends on 6) The device management method according to claim 6, wherein the device management method further comprises: verifying the binding termination instruction by the electronic device using a public key of the first server to determine whether to terminate binding. ### Claim 9 (depends on 6) The device management method according to claim 6, wherein the sending, by the electronic device, the registration information instruction to the second server to execute binding comprises: receiving, by the electronic device, a registration-permitting instruction and a public key from the second server. ### Claim 10 (depends on 9) The device management method according to claim 9, wherein the exchanging of the data information between the electronic device and the second server comprises: verifying the data information by the second server using the public key of the electronic device in the registration information instruction to determine whether to receive the data information.
