Unable to import large Confluence space export

Question

Hi, I exported a space from another Confluence as an XML file (~14 GB) and I’m trying to import it into our Confluence Cloud site.
The upload/import fails with “We had some trouble uploading your space export file”.
Is there a size limit for space imports, and what’s the recommended way to migrate a space of this size (for example, splitting it)?

Hi Kris,

Thank you for your answer, CSV will only work when exporting an entire space, I only export a few pages/folders so I'm using XML format.

Hi @Tom

If it's a Cloud to Cloud export-import, you can try exporting a space as a CSV file, which you can then import to the target site.

These large exports often result in timeouts.

One thing is to try multiple times.

However your best bet is to contact Atlassian support directly.
