For any further details or technical concerns, contact us.

To use the Confluence Cloud Migration Assistant, you need to be on Confluence Server or Confluence Data Center version 5.10.0 or later. If you're on a version earlier than this, you'll need to upgrade before you can use the Migration Assistant.

If you're on an unsupported Server or Data Center version and don't have active maintenance on your license (which is required to upgrade), you can use a free trial license to upgrade in preparation for your migration. Learn how to migrate to Cloud with an expired license


If you’re migrating Confluence and need to integrate Bitbucket Server or Bamboo, refer to the Application links version matrix to check you’re using a compatible version of Bitbucket Server or Bamboo before you start.
