Before start

We recommend reading this Atlassian article to plan your migration.
Please check that you have Discussion the latest version "2.4 for server and 1.0 for cloud" installed in both your instances (having previous versions in any of them won't trigger the discussion migration; it will just migrate confluence space without discussion data).
Make sure discussion is in the list of the "Needed in cloud" apps in the migration assistant.
Make sure that confluence users have valid mail addresses that are the same in their cloud counterparts

Migration process

Make sure that the Confluence Cloud Migration Assistant (CCMA) is updated to its latest version before proceeding with the migration process.
Use the Confluence Cloud Migration Assistant app to migrate everything you need from Confluence server to cloud. Confluence Cloud Migration Assistant explains in detail the step-by-step procedure to migrate the required content.
Select the spaces and the users that you want to migrate
With every migrated space the related discussion will be migrated with its Discussions, categories, contributors...
Each migration has 2 major steps

1 - Migrate Confluence data (Spaces, pages, users)

2 - Migrate discussion data (categories, discussions...)

That's it ! A new space discussion will be migrated.

The migration process ends once the migration assistant reaches 100% in the migration dashboard.
