Tracking existing changesets
Batch Changes allow you not only to publish changesets but also to import and track changesets that already exist on different code hosts. That allows you to get an overview of the status of multiple changesets, with the ability to filter and drill down into the details of a specific changeset.
Importing changesets into a batch change
To track existing changesets in a batch change you add them to the batch spec under the
importChangesets property and apply the batch spec.
The following example batch spec tracks multiple existing changesets in different repositories on different code hosts:
name: track-important-milestone description: Track all changesets related to our important milestone importChangesets: - repository: github.com/sourcegraph/sourcegraph externalIDs: [15397, 15590, 15597, 15583, 15806, 15798] - repository: github.com/sourcegraph/src-cli externalIDs: [378, 373, 374, 369, 368, 361, 380] - repository: bitbucket.sgdev.org/SOUR/vegeta externalIDs:  - repository: gitlab.sgdev.org/sourcegraph/src-cli externalIDs: [113, 119]
See “Creating a batch change” on how to create a batch change from the batch spec.
Once you’ve created the batch change you’ll see the existing changeset show up in the list of changesets. The batch change will track the changeset’s status and include it in the overall batch change progress (in the same way as if it had been created by the batch change):
