一次数据库迁移

场景：从mysql 5.1.59版本迁移数据到5.5.24，在启动时出现数据库启动失败的问题！ERROR日志信息如下：
(1)在远数据库停止服务
(2)用scp吧mydata，innodb_ts, inodb_log文件夹下的所有文件拷贝到目标服务器；
(2) 在目标数据口中配置my.cnf, 启动目标数据库

解决方法：
 mysql_upgrade -d /data1/mysqldata2/mydata -f -S /data1/mysqldata2/sock/mysql.sock -uroot -pXXXX
注：执行时必须在数据库启动的条件下才能执行，不然是无效的！

原因：目前还不清楚，如果有哪位高手知道，指点一下！
