Trying to migrate from Confluence Server version 5.7 to Confluence Cloud 1000.0.0-ed545e62de50.
Confluence Cloud Migration Assistant supports 5.10 and after, I'm on 5.7 so this is not an option.
Attempting an XML export and space import is also not an option since it states it "will not work if you are importing from server version 6.13 or earlier"
What other options do I have?
