The primary domain indicates the top-level domain in the domain map.

## Vorbereitungen

## Warum und wann dieser Vorgang ausgeführt wird

The primary domain cannot have a parent domain and must have at least one child
domain. There can only be one primary domain at a time. If you select another domain
as the primary domain, it overrides the previous primary domain.

## Prozedur

1. Navigate to AllDomain AdminDomains.
2. Select the domain you want to be the primary domain, for example, TOP.
3. Select the Primary check box.
4. Click Update.
