Confluence provides two types of export option,
Full Export(Includes comments & attachments)
Custom Export(Includes comments)
From my part, custom export is successfully migrated.
But While i make Full Export, i provides below error
Reason for checking full export option, is that it includes attachments where as in custom export, it does not include attachments.
For example(custom export)
Am attaching word document to a page in confluence.
After attach it will generate a download link.
Migrating page to XWiki.
XWiki displays the download link. Not the attachment.
And download requires Atlassian credentials.
Attached sample.zip file in task.
