Hi, we are facing out a space but would like to keep the blog and its content. Is this possible, somehow?
Yes, you can do that as if it was a page, basically. In the blog, you click on the three dots on top in the Conflence menu and click “Move”. You will then see a dialog in which you can choose the space you want the blog to live in.
Please note: You’ll need the ‘Delete blog’ permission in the current space, and ‘Add blog’ permission in the new (destination) space to do this.
Here the detailed info in the Atlassian documentation: Blog Posts | Confluence Data Center and Server 8.0 | Atlassian Documentation
