I need to migrate a Jira and a Confluence server.
The problem is that I have a lot of projects and issues in Jira and many spaces and pages in Confluence.
The new servers are already set up with users and configuration, so I cannot perform a system import, and doing it by hand is not an option because of the volume.
How can I migrate each of them without deleting any settings or users?
I have the XML backups of both old servers.
Please help — it seems impossible!
