The annual tournament looked likely to fall off the calendar when it lost its previous sponsor, but it has been hastily resuscitated.
The Cosafa Senior Challenge Cup will have a formal launch on Thursday, as the competition goes ahead for a 12th successive year.
Sponsorship comes from the government of South Africa's Mpumalanga province, where the tournament will be hosted.
It will also see the field expanded to 14, with the entry of the Comoros Islands, and it will be played in a knockout format, in a bid to cut costs.
The top six ranked countries, Angola, Botswana, Mozambique, South Africa, Zambia and Zimbabwe, will not participate in the first phase.
The Comoros Islands, Lesotho, Madagascar, Malawi, Mauritius, Namibia, Seychelles and Swaziland will be drawn into two groups of four for the first phase of the tournament from 19-24 July.

There will be six successive days of double-header matches, and the two group winners will advance with the top six to the quarter-finals on 26 and 27 July.
