Attachment file lost, after changed to new server

Submitted by matekhong on

Hi there!

I've changed web issue server to new one
I've used FTP to copy and replace in new server path
But when I refer to attached file in web issues I couldn't open it, I've check file path via FTP the attachment file still existing in file path but even I tried to open it direct from file path I couldn't open it.

How can I restore this attachment file?
