按照上面的function执行顺序执行即可。涉及到需要改动的table有pre_forum_thread，pre_forum_post，pre_forum_forum，pre_common_stat，pre_common_member_count，pre_forum_post_tableid
详见：http://www.gforetell.com/?/question/188#reply1
同步后出现一个问题。在论坛里发主题的时候会报主键重复错误，查看后得知。2.5版本的pre_forum_post里面pid不是自动增长的，在做插入操作的时候会从pre_forum_post_tableid里面取得最大的+1，改了下最大的就解决了。
之后又出现了一个问题。jforum里面的帖子内容是包含html标签的，但是直接同步到discuz后会直接在页面上出现标签。需要在管理端的“论坛”-“板块管理”-“帖子选项”中将相应版块的“允许使用HTML代码”开启。
