MySQL拒绝启动

我最近升级了XAMPP，很愚蠢，可能只是简单地将我的旧mysql/data文件夹复制到了新的安装中。我不确定我以前运行的MySQL是什么版本，但它可能是5.1。新版本是5.6。无论何时启动MySQL，都会出现以下错误：

2014-11-05 23:31:04 8784 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace db_name/table_name uses space ID: 2 at filepath: .\db_name\table_name.ibd. Cannot open tablespace mysql/innodb_index_stats which uses space ID: 2 at filepath: .\mysql\innodb_index_stats.ibd
InnoDB: Error: could not open single-table tablespace file .\mysql\innodb_index_stats.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.

我从和其他人那里知道，删除ibdata1和ib_logfile0文件暂时解决了这个问题，但每次启动XAMPP/MySQL时我都需要这样做。是否有办法永久解决此问题？

能否创建整个旧数据库的mysqldump，恢复重新安装新版本的MySQL，并从转储中恢复？删除ib_logfile0/1在某些情况下可能会有所帮助，但不要删除ibdata1。从那以后你就完蛋了。它或者保存所有实际数据，或者如果启用了文件表，它将保存指向各个ibd文件的内部字典指针。Hmmm。。我链接到的那个问题建议删除ibdata1，这个答案得到了81票。但事实上，我的db从…起就表现得更奇怪了。。。我想。。。我宁愿避免重新安装。我想知道是否有办法将dbs从5.1升级到5.6…第三条评论建议它会在这个过程中删除你的数据，确实如此。哦，我不怀疑。我想重新安装是唯一的办法。
