Introduction

This document describes the best practice of using Percona XtraBackup to migrate and synchronize the MySQL database data.

This solution is especially applicable to the scenario where MySQL is migrated from an x86 server to a Kunpeng server while maintaining service continuity of MySQL's primary/secondary replication mode.

Percona XtraBackup is a MySQL hot backup tool. It performs full backup, incremental backup, and restoration from backups without interrupting database services, ensuring data consistency and recoverability.

To migrate the MySQL database from an x86 server to a Kunpeng server, install and run Percona XtraBackup on both of the servers.
