Oracle recommends that you clean up your Oracle Analytics Cloud environment before you migrate to Oracle Analytics Server as the more content you have, the more time it takes to migrate. Deleting any old or redundant catalog content and removing extinct users makes the migration smoother and faster.

1. Remove extinct users and groups from the identity store as this also reduces the size of the snapshot and speeds up migration.
2. If you configured usage tracking, review the usage tracking data to identify unused objects.
3. Delete catalog content (workbooks, analyses, dashboards, reports) that you no longer need or don't want to migrate to Oracle Analytics Server from your personal folders and shared folders.
4. Delete unused or old datasets, data flows, and sequences that you don't use.
5. Delete unused database connections that you don't need anymore.
6. Delete unused objects in your semantic model that you don't want to migrate.
7. Delete objects that Oracle Analytics Server doesn’t support, such as data replications.
8. Invite other users to complete the same cleanup tasks.
