How to Import a big Confluence Cloud backup into a another Cloud Site

I have a backup zip file of a Confluence Cloud site that has a size 7.9 Gb, and an XML file of 268 Mb.

When I try to import the backup into a new Confluence site, I get an error due to the XML file size and a broken link to "alternative methods".

I know now that the limit is 200 Mb, but when doing a google search, all I find are guides for migrating from self-hosted sites to the cloud version of confluence.

How can I import a cloud site backup of more than 200 MB, on another cloud site?

PD: The site from which the backup was taken, no longer exists.

Thank you @Fabio Racobaldo _Herzum_. Seems quite complicated, that's too bad.

Do you know how can I split the whole backup, into smaller spaces, that I can import one by one?

Hi @BernalCarlos ,

please take a look to the following article https://confluence.atlassian.com/cloudkb/migrating-from-confluence-cloud-to-confluence-cloud-691011969.html

Do you need to merge two different instances or restore the whole target instance?

I found a ticket in the Atlassian backlog https://jira.atlassian.com/browse/CONFCLOUD-40449 resolved with "Won't fix" resolution. 

Workaround

  • Reduce space size by curating and archiving older data into backups to meet compliance needs.
  • Break down larger spaces into smaller spaces that meet the ~200MB size limit for imports.

Hope this helps,

Fabio

hey @BernalCarlos , ufortunately you need to perform a full backup and then import one by one

Mmm... this is becoming way too hard, I'm trying to restore the backup on a local confluence instance, but I keep finding one problem after another, it looks like Attlasian doesn't care about this process at all.

After finally setting up a local Confluence instance, the backup fails due to UTF-8 encoding: https://jira.atlassian.com/browse/CONFSERVER-78782

Once the UTF-8 encoding is solved, comes a problem with a property that is not supported on non-cloud Confluence: https://jira.atlassian.com/browse/CONFSERVER-60453

After doing the suggested workarounds, the import is still unsuccessful. Now due to some non-whitespace characters.
