We're in the middle of moving all our documentation to a new instance of Confluence Cloud after a corporate separation. Most of our documentation was contained in a space on the old Confluence wiki that we had full export permissions for, so that was no problem to bring into the new space. The problem is some API documentation that was hosted in a space we didn't have export permissions for.
Eventually we managed to get those pages copied over to the space we had export permissions for, and made a second export containing just those pages. However, there appears to be no good way to import this into our new Confluence instance. Because the export has the same space key as the pages we've already imported, it looks like Confluence won't import the file as-is. The suggestion in the docs is to move the pages into a new space and import that instead, but we also have no permission to create new spaces on the old Confluence.
The best option I can think of at the moment is to either a) move all the wiki pages in our NEW Confluence to a temporary space, import the new export file to the existing space, move those pages to a new permanent home, then move the original wiki pages back; or b) with a throwaway email address, start a new Confluence trial, import the XML file to THAT space instead, move the files into a new space, re-export to XML, then import that into our current space.
Neither option seems very direct and I don't know if there are any gotchas to opening a throwaway trial account for this purpose. Are there any better options?
