AI Technical Summary

Technical Problem

When performing data migration, the existing technology directly migrates large-scale data, resulting in a long migration time.

Method used

By slicing the transaction data in the original database based on the characteristics of the demand party to be migrated, the slice data is obtained; according to the amount of data of the storage resources occupied by the slice data in the original database, the slice data is divided to obtain grayscale batch data and formal batch data; after verifying the correctness of the migration process through grayscale batch data, the formal batch data is migrated from the original database to the target database in batches.

Benefits of technology

By slicing, classifying, and migrating large-scale data in batches, the migration time is shortened and the efficiency of data migration is improved.

Abstract

The invention discloses a data migration method and device, equipment, a storage medium and a computer program product, and relates to the technical field of data migration, and the method comprises the steps: carrying out the slicing of transaction data in an original database based on the features of a to-be-migrated demand side, and obtaining the sliced data; dividing the slice data according to the data size of storage resources occupied by the slice data in the original database to obtain gray scale batch data and formal batch data; and after the correctness of the migration process is verified through the gray scale batch data, migrating the formal batch data from the original database to the target database in batches. The data migration time is shortened.
