Large corporations work with legacy systems to standardize the execution of activities, support, data formatting and communication between different sites around the world. However, some companies in certain countries have been unable to integrate these systems due to a number of factors involving cultural aspects, local legislation and infrastructure. With the arrival of the Fourth Industrial Revolution, also known as Industry 4.0, there is a need to deploy digital projects that have a dependency relationship with legacy systems in acquiring and managing information making it more accessible to the user. In addition, this integration needs to be synchronized with other countries so as not to lead to uneven maturity among organizations, leading to difficulties in adopting I4.0 in different plants around the world. The objective of this article is to elaborate an evaluation methodology between legacy and local systems, using multi-criteria decision-making methods (MCDM/A), in order to verify if both attend the specifications of the organization's digital transformation projects. As a way to evaluate the proposed model was used the case of an automotive company located in Brazil for more than 20 years that has one of its units in South America (Colombia) with local systems that are bringing numerous difficulties of implementation of projects geared to I4.0. With the support of the MCDM/A methods, it was noticed that some local systems would be able to attend the scope of the projects since it would allow a flexibilization to customize certain points of integration.
