I am trying to import (merge) Spaces from one Cloud Confluence instance to another. I have encountered an issue where there are Spaces in that use the same KEY identifiers. I have tried editing the entries.xml and exportdescriptors file and even run the clean up tool for the entities file but, keep getting the: "com.atlassian.confluence.importexport.ImportExportException: Unable to complete import: Content is not allowed in prolog." error.
Help would be most appreciated with this!
Thanks
