[do kim]

im trying to export from confluence server to confluence cloud. 

it says i need to use the migration assistant in order to do that. 

Does the server from where i want to export need internet access in order to accomplish this?

Hello, if necessary.

The confluence migration assistant performs a backup of the server instance and generates the information in the cloud environment using the rest API endpoints, so it is necessary for the server to have access to the cloud instance and for the user performing the migration to have permissions to write about migrated spaces

If your Confluence Server site is behind a firewall, you'll need to allow access to the domain: atlassian.com. You also might need to allow access to other Atlassian domains.
