Licenses needed for migrating projects from Jira Server to Jira Cloud
The Cloud Migration Tool is a free app, and you don’t need a license for it. Yet, to perform migrations of projects and issues from Jira Server instances to Jira Cloud sites, you need to pair the Cloud Migration Tool with Configuration Manager for Jira Cloud, a paid app. In that case, you need to install Configuration Manager for Jira Cloud on the destination cloud site and provide a license.
Separate Configuration Manager licenses are required for each destination Jira Cloud site where you would like to migrate your projects and issues.
In summary:
Cloud Migration Tool is a free app, and you don’t need a license after installing it.
Configuration Manager for Jira Cloud is a licensed app, and you need to have separate licenses for each Jira Cloud site where you’re planning to install and use it.
