Abstract

The invention discloses a data migration processing method and device. The method comprises the following steps: locking a customer; after the client is successfully locked, exporting migration data of the client from the source system; performing data conversion on the migration data to obtain target data, the data conversion being to convert the migration data into the target data of a target system according to a conversion relationship in a data mapping table; performing data verification on the target data; after the data verification succeeds, importing the target data into the target system; and unlocking the client. According to the method, a series of processes such as locking, verification and unlocking are designed to be scheduled for multiple systems, in the migration process with the large client amount and concurrency amount, the client state consistency in the data migration process is guaranteed, and then the technical problem of data consistency in the data migration process is solved.

Description

technical field [0001] The present invention relates to the field of data migration, in particular to a processing method and device for data migration. Background technique [0002] During the data migration process, data consistency needs to be ensured during data migration from the old system to the new system. Most of the existing data migration solutions use downtime migration. During the downtime migration process, customer transactions will not be performed, and customer data will not change. Therefore, data consistency processing is not required. In some online migration scenarios, data changes are recorded during the data migration process and synchronized when migrating to the new system. At present, there is still a method of calling the corresponding locking interface of the associated system to ensure data consistency. [0003] Compared with other existing systems, this system has the following two difficulties. One is the large scale of data migration. The ...
