Another unique ChangeMan ZMF feature is the ability to freeze Change Packages. When the Change Package is ready for the next phase of the change implementation lifecycle, a freeze is performed to prevent further modifications. The freeze also positions the Change Package for promotion or approval. Traditional methods accomplish this function by moving components from the development libraries to a separate set of libraries or, in some cases, separate environments. ChangeMan ZMF controls your updates in conjunction with your security system, so component movement is no longer necessary.

If further modifications are required, you can unfreeze a Change Package, and the approval process is reset.
