Migrate error from 5.10.0, space deleted in server

[Bruce Yen]

I'm migrating from server (5.10.0) to Cloud (free version).

It errored out with: 

     An unexpected error occurred during step: Migrating attachments. Error: null

 (deleted in Server). Spaces were deleted.

Any idea or suggestion?

Hello Bruce,

Thank you for raising this with Atlassian Community. I hope you are doing well. 

I assume you are using the Confluence Cloud migration assistant. It seems that somehow in the attachments step, the spaces are deleted. We will need to review the migration logs to discern what is happening.

From the Contact Support page, select Migration Support and send your case straight to the migration team. There you can provide them with your migration logs, and we can investigate the problem.

Please share with us here once you determine the problem in case someone else has the same issue. If you have any trouble raising that ticket, please let me know!

Take care,

Shannon
