This paper has the objective to propose the usage of multicriteria decision making methodology, with focus on the MACBETH method in arder to support the network migration, based on information extracted from the financiai reports published on the public internet. This paper will show the study of two companies that have m igrated to MPLS in the last five years, buildlng the MACBETH Model from information present on the Financiai Report at the time of contract was signed and validating the information extracted with executives from the commercial and technical departments who lived through that period in the company. Within this scenario it can be verified that MACBETH Method once provided with the correct information that reflects the period the cornpany is living rnay help executives to decide if they should migrate ar not migrate their network === Gestores de telecomunica??es e TI precisam estar sempre atentos aos rumos da organiza??o e com isso procederem a mudan?as necess?rias nas estruturas e redes de comunica??o que subsidiam os neg?cios da empresa. A tomada de decis?o a respeito da migra??o de tecnologias n?o dever ser efetuada sem um m?todo consistente que as subsidie, livrando o gestor de riscos e preju?zos empresariais que podem ser minjmizados quando uma abordagem estruturada elencando os principais crit?rios a serem considerados ? utilizada. Este trabalho tem como objetivo propor o uso de metodologia para tomada de decis?o multicrit?rio, com foco no m?todo MACBETH, para subsidiar a migra??o de plataformas de redes de telecomunica??es. Com base em informa??es oriundas de boletins financeiros disponibilizados publicamente na Internet. O trabalho analisa duas empresas que migraram para plataforma MPLS, construindo a estrutura do m?todo MACBETH a partir das informa??es obtidas nos boletins financeiros dessas organiza??es e validando a an?lise com dados obtidos de gerentes das ?reas comerciais e de tecnologias que vivenciaram esse per?odo. Dentro desse quadro, considerou-se que o m?todo MACBETH, uma vez alimentado com informa??es corretas que reflitam o momento da empresa, pode orientar gestores a decidirem se devem ou n?o proceder ? migra??o de suas bases tecnol?gicas
