More details
The Confluence Cloud Migration Assistant is the recommended way to migrate to Confluence Cloud. As you plan your migration, the app allows you to assess your on-premise app usage and develop an app migration strategy. Once you’re ready to move data, the Confluence Cloud Migration Assistant also allows you to migrate spaces, users, and groups to cloud.
Important details:
- Set up a Confluence Cloud site before migrating. If you haven’t already, start a free cloud migration trial.
- This app requires that your Confluence Server or Data Center runs on version 8.9.1 or above
- Review the server to cloud migration guide for an overview of the migration process.
*Note: CCMA 3.3.6 and older versions are unsupported. Upgrade to the latest CCMA version for optimal performance.
We’re continuing to invest in the Confluence Cloud Migration Assistant and adding additional functionality. For more information on what we’ve got planned, visit the migration tooling section of the Atlassian Cloud Roadmap.
