Mar*_*rov 5 mysql windows upgrade
我在 Windows 8 上，我的 SSD 损坏了，我在新驱动器上安装了 Windows。我在 MySQL 5.6.12 之前有过，现在我安装了 5.6.17 并尝试移动整个数据目录。MySQL 安装位置与之前相同。但是当我启动它时，我收到以下错误：

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

非常感谢您的宝贵时间。
可能帮助您解决此问题的建议：
1) 从数据目录示例中进行备份，将数据文件夹复制到 data_old 文件夹，以防万一出现问题，您可能需要它
my.ini2）从文件中进行备份
3）复制默认内容my.ini并将其粘贴到您正在使用的内容中（不要忘记编辑basedir和datadir端口号 或编辑当前内容。
4) 从datadirib_logfileX中删除
5）尝试启动服务。
6）使用正常转储推荐mysqldump -uroot -Pport -ppassword --all-databases>dump.sql
7) 将其恢复到另一个SID。
mysql_upgrade8)在新的SID上运行
