Migration from server/DC to cloud

Description

Before migrating your SQL for Confluence app content from server to cloud, we recommend reading this Atlassian article to plan your migration. 

Administrators must ensure that the following feature flag is enabled in the server instance as a part of the pre-migration setup:

  • migration-assistant.app-migration.feature: <Confluence_URL>/admin/darkfeatures.action

Refer to the Getting started page from Atlassian for more information about the prerequisites for the migration.

This page explains:

  • Migration process
  • Differences between the server/DC and cloud version of the app

Migration process

  • Confluence instance migration - Use the Confluence Cloud Migration Assistant app to migrate everything you need from Confluence Server to Atlassian Cloud. Confluence Cloud Migration Assistant explains in detail the step-by-step procedure to migrate the required content. As mentioned in the previous section, Atlassian does this job for you in most cases.
  • App installation - Install the app from Marketplace.
  • All global configuration data in the Configuration page are transferred from the server/DC instance to the cloud instance.
  • Profile configuration data migration is not supported in this release. Administrators are required to manually create profiles as required to avoid issues rendering SQL content on Confluence pages.
  • If multiple migrations are performed on the same cloud instance, the latest migration takes precedence.
  • Any subsequent migrations performed on the same cloud instance only adds or merges the data, but does not delete any existing data.

Important information:

  • The migration of data from server/DC to cloud is an independent process from app installation or configuration in your cloud instance. We recommend that administrators verify that all your data (configuration as well as your Confluence pages) are displayed properly after the migration process is completed. Please report any issues immediately.
  • We capture certain details, excluding private user data or any personally identifiable information, during the migration process to help us improve our app continually. Refer to Analytics data to know more about the what information is collected.
