The new migration features were introduced in Gitea 1.9.0. It defines two interfaces to support migrating
repositories data from other git host platforms to gitea or, in the future migrating gitea data to other
git host platforms. Currently, only the migrations from github via APIv3 to Gitea is implemented.
First of all, Gitea defines some standard objects in packages `modules/migrations/base`. They are
`Repository`, `Milestone`, `Release`, `Label`, `Issue`, `Comment`, `PullRequest`.
`Repository`, `Milestone`, `Release`, `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 get all kinds of repository informations.
- You should implement a `DownloaderFactory` which is used to detect if the URL matches and
- You should implement a `DownloaderFactory` which is used to detect if the URL matches and
create a Downloader.
- You'll need to register the `DownloaderFactory` via `RegisterDownloaderFactory` on init.
```Go
type Downloader interface {
SetContext(context.Context)
GetRepoInfo() (*Repository, error)
GetTopics() ([]string, error)
GetMilestones() ([]*Milestone, error)
GetReleases() ([]*Release, error)
GetLabels() ([]*Label, error)
GetIssues(start, limit int) ([]*Issue, error)
GetIssues(page, perPage int) ([]*Issue, bool, error)
GetComments(issueNumber int64) ([]*Comment, error)
GetPullRequests(start, limit int) ([]*PullRequest, error)
GetPullRequests(page, perPage int) ([]*PullRequest, error)
GetReviews(pullRequestNumber int64) ([]*Review, error)
}

Currently, only a `GiteaLocalUploader` is implemented, so we only save downloaded
data via this `Uploader` on the local Gitea instance. Other uploaders are not supported
and will be implemented in future.
