When you import a business issue that already exists in PAD, you do not override the projects that are in the existing business issue. The projects are saved under a different name , for example Projectname_1. Typically, you import business issues when they need to be moved between different instances of the Pega 7 Platform because of the system upgrades, data center migrations, or capacity increase.
In PAD, click the Manage Resources section.
Click Import business issue.
Select a business issue and click Submit.
