Success Case: How TTY2000 Migrated the Legacy Systems of a Major Brazilian Insurance Company from the IDMS Environment to DB2, Ensuring Operational Continuity

The Challenge: To migrate the legacy applications of Minas Brasil Seguradora, developed in the 1990s with CA-IDMS/R and ADS/O, to the DB2 environment, considering:
  • Expiration of the IDMS licensing contract
  • Technological modernization already carried out by the corporate group
  • Need to maintain operational continuity without risks

The goal was to eliminate dependence on the CA-IDMS/R environment and integrate the insurance company into the group's modern technological environment.

  • Thorough analysis of all routines in production
  • Identification of active systems and obsolete components
  • Optimization of migration effort
Conversion of CA-IDMS/R Records to DB2 Tables

Translation of ADS/O, COBOL, PL1, and EASYTRIEVE Programs
  • Adaptation of ADS/O dialogs to BMS/CICS standard
  • Conversion of programs for integration with DB2
  • Adjustments in JCLs for the new environment
Execution of Unit, Integration Tests, and Final Validation
  • Individual tests per program
  • Integration tests between systems
  • Final validation with monitoring by the insurance company’s team
Technical Training in DB2 SQL for the Insurance Company Team
  • Training program divided into two modules:
