Preferably, the acquisition result is written into the environment configuration library in the step S3, and the environment synchronous monitoring program is used for monitoring, so as to keep the parameters of the source system and the parameters of the target system consistent.
Preferably, in step S4, the container image of the source system is migrated to the target system, and parameter configuration needs to be performed based on the configuration library.
Preferably, the client desktop application in step S6 includes a browser, a layout file, a streaming file editor, and an electronic signature application.
Preferably, in step S7, the client desktop image needs to be made while the client desktop container is started on the target system.
The invention has the beneficial effects that:
1. the application system packs the source system at one time, then unpacks and packs again after migrating to the domestic environment, so that the application system can adapt to the domestic environment and avoid the influence of environmental difference on program operation;
2. by using a data log synchronization technology, incremental data can be synchronized to a domestic database on a target system under the condition that the system operation is not influenced;
3. the CRIU tool is used for collecting the running state parameters of the container, configuration parameters can be provided for secondary packaging of the container, and the consistency of the container state is ensured;
4. the client migration mode based on the desktop container can ensure that the client control of the application system is completely transplanted, and the situation that the application cannot normally run due to inconsistent control configuration parameters is avoided.
