直接应用两个的struct.h 把改转的转了就行了。

具体可以参见 FB2000目录的 bbssrc/src/util/upgrade

我就是从3.0K UESTC 升级到2000v1219的.

【 在 chrisduo (风筝) 的大作中提到: 】
: 在REDHAT7.2下升级FB2000版本是1219
: 按照说明升级密码文件.passwd时候,没什么问题
: 但是拷贝覆盖掉时候
: 发现500多个用户只有大概30个用户成功转换了
: 其他的都变成乱七八糟的了,也就是丢失了
: 而且能成功转换的用户每次登陆都必须从新填写一次生日的资料
: 而且注册新用户的时候就吊线
: 请大牛指点啊!!!!!!!
