This paper presents the migration strategy that is being used by Public Safety Secretariat of Mato Grosso (SESP-MT) to convert its legacy systems that are monoliths to a microservice oriented architecture. Despite the standards already defined for a microservice project, it is difficult to find successful processes and practical experiences reports in gradual migration from a monolith to a microservice architecture, especially regard to the legacy database split and separation. Our research group obtained successful results applying the database sharing strategies and migration process described in this paper through a period of monolith and microservice coexistence. This is the contribution of this paper.
