想把网站搬到另一台电脑，拷贝了webapps下的网站页面文件夹粘贴到新电脑的相应目录下；然后Mysql备份了网站数据库文件，在新电脑的Mysql下恢复成功；然后启动Tomcat后主页能正常显示，但是点击具体的内容链接则出现错误。 请问这样的备份迁移可行吗？还应该修改或设置什么地方？ 另外，俺也懂可以在后台备份滴。但是实际情况如这个帖子一般http://bbs.jeecms.com/bug/13369.jhtml，看来是jeecms2012和Mysql*有点兼容问题。很不幸的是，最初做网站俺选择了Mysql*，所以一备份就出错，而且看不太懂你们在帖子里讲的改程序的解决办法，所以目前想采用复制粘贴数据的形式备份迁移，结果还是不可行。 求指点。

点击具体的内容链接则出现错误？能发下错误信息吗？
