I am trying to migrate one space from our on-premises installation to Confluence Cloud. Everything is set up:
- I am choosing to Migrate spaces (I only select one space)
- I am choosing to Migrate users related to the selected spaces
- Apps: None. Even though I have set the Draw.io Confluence Plugin to "Needed in Cloud": it doesn't show up in the migration and None is the only option
The export of the space fails at 40% in both development and production environments with the following error in the logs:
