Discuz!2.0/2.2F升级到Discuz!4.0正式版的步骤

我在从2.2F升级到4.0版时，前面1-11步都是成功的，第12步时提示如下错误：
请各位帮忙一下是不是可以从phpadmin长级，该如何做？

暂停下来，打开升级程序，找到

1. ALTER TABLE cdb_forums CHANGE icon icon CHAR(50) NOT NULL, CHANGE name name CHAR(50) NOT NULL, CHANGE description description CHAR(255) NOT NULL, CHANGE moderator moderator CHAR(255) NOT NULL, CHANGE lastpost lastpost CHAR(100) NOT NULL, CHANGE password password CHAR(12) NOT NULL, CHANGE viewperm viewperm CHAR(100) NOT NULL, CHANGE postperm postperm CHAR(100) NOT NULL, CHANGE getattachperm replyperm CHAR(100) NOT NULL, CHANGE postattachperm getattachperm CHAR(100) NOT NULL, CHANGE threads threads MEDIUMINT(8) UNSIGNED DEFAULT '0' NOT NULL

复制代码

删除这一段代码后继续升级，不过不能重新升级，一定是继续升级～

按照你的方法倒是成功了，但在运行upgrade4.php时提示：
您当前数据库数据版本不是3.0,无法升级

现在该怎么办？

你是升级到 Dz3.0 了吗？用 dbcheck 看看是不是标准结构的 Dz3.0
