進行操作前，請備份數據庫

一本地轉到遠程

1論壇后臺--全局--上傳設置--啟用遠程附件

2將本地附件目錄data/attachment里面的文件夾移動到遠程服務器上

3數據庫執行sql語句

論壇的（0表示本地，1表示遠程，）

update pre_forum_attachment_0 set remote=1 where remote=0;

update pre_forum_attachment_1 set remote=1 where remote=0;

update pre_forum_attachment_2 set remote=1 where remote=0;

update pre_forum_attachment_3 set remote=1 where remote=0;

update pre_forum_attachment_4 set remote=1 where remote=0;

update pre_forum_attachment_5 set remote=1 where remote=0;

update pre_forum_attachment_6 set remote=1 where remote=0;

update pre_forum_attachment_7 set remote=1 where remote=0;

update pre_forum_attachment_8 set remote=1 where remote=0;

update pre_forum_attachment_9 set remote=1 where remote=0;

門戶的

update pre_portal_article_title set remote=1 where remote=0;

update pre_portal_attachment set remote=1 where remote=0;

update pre_portal_topic_pic set remote=1 where remote=0;

相冊的{相冊表中的remote取值還有一種情況為remote=2(論壇附件圖片保存到相冊)}

update pre_home_pic set remote=remote+1;

二 遠程轉到本地

后臺關閉遠程附件設置，將附件移動到本地服務器的 data/attachment目錄后執行sql即可

0表示本地，1表示遠程，

update pre_forum_attachment_0 set remote=0 where remote=1;

update pre_forum_attachment_1 set remote=0 where remote=1;

update pre_forum_attachment_2 set remote=0 where remote=1;

update pre_forum_attachment_3 set remote=0 where remote=1;

update pre_forum_attachment_4 set remote=0 where remote=1;

update pre_forum_attachment_5 set remote=0 where remote=1;

update pre_forum_attachment_6 set remote=0 where remote=1;

update pre_forum_attachment_7 set remote=0 where remote=1;

update pre_forum_attachment_8 set remote=0 where remote=1;

update pre_forum_attachment_9 set remote=0 where remote=1;

update pre_portal_article_title set remote=0 where remote=1;

update pre_portal_attachment set remote=0 where remote=1;

update pre_portal_topic_pic set remote=0 where remote=1;

update pre_home_pic set remote=remote-1;
