Specifically, the service of the service system corresponding to the individual page configuration data may not be deployed in the first data server 102, and for the service systems in which the service is not deployed in the first data server 102, the data first front-end display unit 101 of some service systems may be directly acquired through an external interface, and of course, different external interfaces may be corresponding to different service systems. The first front-end display unit 101 directly obtains the page configuration data from the first service system 201 through the external interface, that is, the second page configuration data described above.
At this time, after the first front-end display unit 101 acquires the second page configuration data, the first data server 102 needs to acquire the second page configuration data from the first front-end display unit 101 and cache the second page configuration data. The migration manner of the cached second page configuration data is the same as that of the first page configuration data, and will not be described herein.

Specifically, the service of the service system corresponding to the individual page configuration data may not be deployed in the first data server 102, and for the service systems in which the service is not deployed in the first data server 102, the data first front-end display unit 101 of some service systems may be directly obtained through an external interface, and the data first front-end display unit 101 of some service systems cannot directly obtain data through the external interface because of a cross-domain problem or a security problem. A third party proxy server 301 performing forwarding is then required to assist in obtaining such page configuration data, i.e. the third page configuration data described above.
After the first front-end display unit 101 obtains the third page configuration data through the proxy server 301, the first data server 102 needs to obtain and cache the third page configuration data from the first front-end display unit 101. The migration manner of the cached third page configuration data is the same as that of the first page configuration data and the second page configuration data, and will not be described herein.
