A legacy domain is the term used for co.za domain names which have been registered with Uniforum SA.
Uniforum SA is the administrator of CO.ZA and prior to the launch of ZA Central Registry's EPP system all CO.ZA domain names were registered with Uniforum SA on their "Legacy System".
With the launch of ZA Central Registry' EPP system, the former Uniforum SA's domain management system was labelled as the Legacy system.
It is possible to register co.za domain names on the legacy system with Uniforum SA.
