How to merge two different Jira Cloud applications together
This Knowledge Base article applies equally to both the Atlassian Server and Atlassian Cloud platforms.
The purpose of this article is to explain how to merge two Jira Cloud applications together, as currently there is no way to do this in the Jira Cloud application interface. By exporting data to temporary Jira Server application, most of the data can be merged together into one Jira Cloud application.
Using project import in this manner has limitations so you may lose data in the migration process. Additional information from add-ons, such as boards, backlogs and sprints in Jira Software, will be lost during the project import.
See the following for further information:
In these steps, we'll follow the steps outlined in the diagram below:
- Follow the Exporting issues page to use the Jira Backup Manager to get the data from Jira Cloud B (this contains the Projects you'd like to import to A). After doing so, go through Migrating from Jira Cloud to Server to setup the Jira Server application, using the backup created from the previous step.
- Create an XML backup from the Jira server instance as per Backing up data and keep it aside. This will be used for project imports.
- Repeat step 1, however use the data from Jira Cloud A and use the same Jira Server application. This means you can skip a lot of the setup and just need to export from the Cloud A application and import to Server.
Using our Restoring a project from backup guide, import the projects from step 2 into Jira server instance.
ImportantIf the attachments are not included, during the project restore, the imported project will not have attachments associated with it.
You cannot restore your attachments separately, as the database entries for the attachments will be missing.
After successfully importing all the required projects, create an XML backup of the Jira Server application using Backing up data. The instructions in Importing issues will guide you through how to restore that backup into the Jira Cloud application, which will have Cloud A & Cloud B in it.
