We have a Confluence Server on an EC2 instance and in attempting to upgrade to Confluence Cloud, our server died, and the upgrade failed.
Do we need to resurrect the server or can we migrate the data directly from the database?
I saw that the Migration Assistant can migrate from Server. I assume this needs a running server to work. Is this the recommended method for this particular scenario, or is there another method we could use?
EDIT: We have an existing cloud site and would like to keep the data that exists there as well.
