# 迁移功能
|
||
|
|
|
||
|
|
完整迁移功能在Gitea 1.9.0版本中引入。它定义了两个接口，用于支持从其他Git托管平台迁移存储库数据到Gitea，或者在将来将Gitea数据迁移到其他Git托管平台。
|
||
|
|
|
||
|
|
目前已实现了从GitHub、GitLab和其他Gitea实例的迁移。
|
||
|
|
|
||
|
|
首先，Gitea在包[modules/migration](https://github.com/go-gitea/gitea/tree/main/modules/migration)中定义了一些标准对象。它们是`Repository`、`Milestone`、`Release`、`ReleaseAsset`、`Label`、`Issue`、`Comment`、`PullRequest`、`Reaction`、`Review`、`ReviewComment`。
|
||
|
|
|
||
|
|
## 下载器接口
|
||
|
|
|
||
|
|
要从新的Git托管平台迁移，需要进行两个步骤的更新。
|
||
|
|
|
||
|
|
- 您应该实现一个`Downloader`，用于获取存储库信息。
|
||
|
|
- 您应该实现一个`DownloaderFactory`，用于检测URL是否匹配，并创建上述的`Downloader`。
|
||
|
|
- 您需要在`init()`中通过`RegisterDownloaderFactory`注册`DownloaderFactory`。
|
||
|
|
|
||
|
|
您可以在[downloader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/downloader.go)中找到这些接口。
|
||
|
|
|
||
|
|
## 上传器接口
|
||
|
|
|
||
|
|
目前，只实现了`GiteaLocalUploader`，因此我们只能通过此Uploader将下载的数据保存到本地的Gitea实例。目前不支持其他上传器。
|
||
|
|
|
||
|
|
您可以在[uploader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/uploader.go)中找到这些接口。
