## Merge versions

`PUT /rest/api/{2-3}/version/{id}/mergeto/{moveIssuesTo}`

Merges two project versions. The merge is completed by deleting the version specified in `id` and replacing any occurrences of its ID in `fixVersion` with the version ID specified in `moveIssuesTo`.

## Get version's related issues count

`GET /rest/api/{2-3}/version/{id}/relatedIssueCounts`

Returns the following counts for a version:

* Number of issues where the `fixVersion` is set to the version.
* Number of issues where the `affectedVersion` is set to the version.
* Number of issues where a version custom field is set to the version.
