Each sub-organization inherits all feature, connector, and custom licenses from the parent organization except for the Organization Hierarchy license and bundle licenses.
When you manage licenses individually, administrators for the parent organization can disable, enable, and modify the expiration dates for the licenses that the sub-organizations inherit. They configure the licenses separately for each sub-organization. Therefore, disabling a license in one sub-organization does not disable the license in other sub-organizations.
Alternatively, if you have the appropriate license, you can automatically synchronize sub-organization licenses with the parent organization. When this license is enabled, each time a license is changed in the parent organization, all sub-organizations inherit the license change.
