如果升级了7.0预览版，又想降回6.23版本的，需要这样操作：

1、在Win系统安装好Xshell软件；
2、DSM7.0开启telnet和ssh，并设置端口；
3、用Xshell打开以admin用户登录DSM7.0，输入 sudo -i 回车，此时会提示输入密码，输入admin的密码，此时就可以获取到临时的root权限；

4、输入 vi /etc.defaults/VERSION 回车，在当前窗口按一次键盘的字母”i”键，利用上下左右的方向键把里面的内容全部删除，然后再输入以下内容，可以复制粘贴：
majorversion=”6″
minorversion=”2″
productversion=”6.2.3″
buildphase=”GM”
buildnumber=”25426″
smallfixnumber=”0″
builddate=”2020/07/01″
buildtime=”06:24:39″

5、确认无误后，按一次键盘的Esc键，输入:wq 回车，就保存退出了；

6、重启群晖；

7、去官网把你的白群DSM6.2.3版本安装包下载到电脑上；

8、群晖重启结束后，在电脑上用Synology Assistant搜索，此时会提示安装系统，手动上传DSM6.2.3安装包进行安装，但安装过程会报错；

9、别担心，再次重复第4点，但要用telnet登录，用户名：root，密码：101-0101，改好文件以后用群晖助手搜索；

10、手动上传DSM6.2.3安装包进行安装，这次就不会报错了；

11、安装完成，进入到DSM6.23的桌面的时候，在控制面板，更新与还原，把之前备份的系统设置还原；

12、降级成功！
