+# Migration Interfaces
+
+Complete migrations were introduced in Gitea 1.9.0. It defines two interfaces to support migrating
+repository data from other Git host platforms to Gitea or, in the future, migrating Gitea data to other Git host platforms.
+
+Currently, migrations from GitHub, GitLab, and other Gitea instances are implemented.
+
+First of all, Gitea defines some standard objects in packages [modules/migration](https://github.com/go-gitea/gitea/tree/main/modules/migration).
+They are `Repository`, `Milestone`, `Release`, `ReleaseAsset`, `Label`, `Issue`, `Comment`, `PullRequest`, `Reaction`, `Review`, `ReviewComment`.
+
+## Downloader Interfaces
+
+To migrate from a new Git host platform, there are two steps to be updated.
+
+- You should implement a `Downloader` which will be used to get repository information.
+- You should implement a `DownloaderFactory` which will be used to detect if the URL matches and create the above `Downloader`.
+  - You'll need to register the `DownloaderFactory` via `RegisterDownloaderFactory` on `init()`.
+
+You can find these interfaces in [downloader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/downloader.go).
+
+## Uploader Interface
+
+Currently, only a `GiteaLocalUploader` is implemented, so we only save downloaded
+data via this `Uploader` to the local Gitea instance. Other uploaders are not supported at this time.
+
+You can find these interfaces in [uploader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/uploader.go).
