Common Services enables you to manage a hierarchy of business units and organizations that is referred to as a tenant service group. A tenant service group (TSG) is used to provide a logical container that contains tenants and other TSGs. It is the building block for a multitenant hierarchy. Generally, this multitenant hierarchy is described as a series of nested tenants, where a tenant is used to manage, monitor, and license products. But mechanically, a tenant is just a TSG. The terms are often used interchangeably.

After you have received information about the transition of your app instance to a tenant, your instance is now a single tenant. You have access to Common Services for subscription management, tenant management, and identity and access management. You do not have access to the multitenant summary dashboards, as those are not applicable and not available for single tenants. See the FAQ if you have more questions about the migration.

Each tenant is automatically assigned a TSG ID, which is primarily for use with service accounts. However, the TSG ID is also used for default login purposes. If you clear your cache, or if you log out of the Strata Multitenant Cloud Manager and log back in, you are logged into the top-level parent tenant with the lowest TSG ID by default. The top-level parent tenant with the lowest TSG ID is likely the first one you created.

The tenant hierarchy limits explain the number of used and unused tenants you can create.
