You can modify match models that are in draft status. When you edit a match model, you create another version of the model.
You can have a maximum of 50 versions for a match model. If the number of match model versions reaches the maximum limit, delete an existing version and create another version, or copy the model to create a new model. To change the maximum limit of model versions, contact Informatica Global Customer Support.
