Attachment problem:DB migration from windows to linux

[bestrick]

I am trying to migrate testlink from windows to linux.I simply exported database form previous database in windows,and the imported database in linux,and then I copyed testlink directory from windows to linux.Everything seems ok except the attachement.I can not download attachment from the new testlink,although I copyed the attachment from previous to [testlink]/upload_area.Please help me how to migrate attachment! Thanks!
