When importing a Project configuration snapshot containing only a single project, you need to select a project on which Configuration Manager to apply the configuration. You can deploy single-project snapshots in two different modes: Merge Project and New Project modes.
For the Merge Project mode, the deployment starts with selecting a target project on which the configuration will be applied. A dropdown will appear on the page from which you can choose any current Jira instance.
For the New Project mode, Configuration Manager creates a project on the target system identical to the source project from the snapshot.
Project Configuration Snapshot
Merge Project Mode
By default, the single-project deployment starts in "Merge Project" mode.
Select a project on which the configuration will be applied.
Configuration Manager allows you to include issue data in project snapshots. Project with Issues snapshots can be imported in "Merge" mode if the target project does not contain any issues or if new issues can be added incrementally. Otherwise, such snapshots are always deployed in the "New Project" mode.
