I moved Confluence to another server as follows:
1- Made an XML backup (no attachment)
2- Made a backup of /var/atlassian/application-data/confluence/attachments --> this might cause the problem below since I only backup attachments folder, not the whole home folder
3- Installed new server
4- Copied this attachments backup to exact same folder
5- Performed Restore XML backup during installation via web interface during installation
Confluence shows all text properly, but all attachments did not show up (images, Gliffy addons, pdf...).
The old server was crashed and crushed. I could not backup the whole old home folder again.
How can we get the attachments to show up?
Thank you for your support.
