A VIP environment has a convenience name assigned to it until the environment is ready for a site launch. All instances of the convenience domain in an environment’s database are replaced by the primary domain as part of the launch process.
The order of launching sites on a multisite requires subsite
1 (also referred to as the “root site”) to be launched first with the primary domain assigned to it.
In the Domains panel of the VIP Dashboard, an assigned primary domain for an environment can be identified by a “Primary” label to the right of a listed domain.
