You can also change the default issue tracker for the selected project and, if a Build integration has been established, a default build server. Selecting a build server is optional, but at least one default issue tracker or code deployment must be selected for your project. A link to enable an issue tracker is provided if the integration has not yet been made in the organization.
Only certain members can create an integration for the organization. See Access Control for more information.
