+## How to migrate data from [CVAT.org](https://cvat.org/) to [CVAT.ai](https://app.cvat.ai/)
+
+Please follow the [export tasks and projects guide](/docs/manual/advanced/backup/#backup) to
+download an archive with data which corresponds to your task or project. The backup for a
+project will have all tasks which are inside the project. Thus you don't need to export
+them separately.
+
+Please follow the [import tasks and projects guide](/docs/manual/advanced/backup/#create-from-backup)
+to upload your backup with a task or project to a CVAT instance.
+
+See a quick demo below. It is really a simple process. If your data is huge, it may take some time.
+Please be patient.
