The method in the embodiment can be applied to an internet of things platform for providing the application system, and the internet of things equipment provides service for the application terminal based on the application system. The internet of things platform can be a cloud platform for providing internet of things services, and receives equipment association data sent by the internet of things equipment. The application end is a user end for providing service by using the application server end and is an actual use end of the device associated data. The application end sends an equipment control instruction to the application server end, determines the equipment to be controlled according to the equipment control instruction, inquires the application system to which the equipment belongs, and sends the control instruction to the corresponding Internet of things equipment through the corresponding application system in the Internet of things platform, so that the equipment is controlled. That is to say, the service object of the internet of things platform is the application server, and the service object of the application server is the application server.
After receiving the data migration request sent by the application control terminal, the internet of things platform determines the internet of things equipment to be migrated according to the data migration request, executes a data migration task, and migrates the equipment associated data of the internet of things equipment from the first application system to the second application system.
The first application system and the second application system can be systems for providing corresponding services of the internet of things, and can achieve management functions of resources such as products, equipment and rules provided by the platform of the internet of things. Wherein the device association data may include: the metadata information of the device infrastructure, such as product definition, device tag, device group, etc., may also include attribute information generated during device runtime, and rule engine data, etc. Where a product may be a collection of devices, it generally refers to a group of devices having the same functionality.

determining the Internet of things equipment subjected to gray level migration in the Internet of things equipment to be migrated according to the gray level strategy of data migration;
and migrating the equipment associated data of the grayscale migrated internet-of-things equipment from the first application system to the second application system.
In practical application, according to a pre-configured gray scale strategy, a part of device-associated data can be migrated first, the accuracy of data migration is verified, and then full migration is performed, so that the data migration is ensured not to cause service damage. The gray level strategy can select a part of the Internet of things equipment to be migrated as the gray level migrated Internet of things equipment according to the requirements of a user, and can also configure the gray level strategy according to the actual needs of an application scene to determine the gray level migrated Internet of things equipment and migrate the equipment associated data of the gray level migrated Internet of things equipment from the first application system to the second application system.
In a possible implementation manner, determining, according to a grayscale policy of data migration, a grayscale migrated internet of things device in an internet of things device to be migrated includes:
