VMS to Linux
FORTRAN: 5 million lines
Real-time application
Intel FORTRAN compilation
VMS system call conversion

The customer, Amprion GmbH, is one of the four transmission system operators in Germany. Sector7 was tasked with converting 5 million lines of a mix of legacy FORTRAN code to Intel FORTRAN running on Linux. The application is tightly coupled to VMS system calls and operates in real time, requiring precision and reliability in the migration process.
- Migration of 5 million lines of mixed FORTRAN code from VMS to Linux.
- Real-time application requiring tight integration with VMS system calls.
- Conversion of VMS system calls and recompilation with Intel FORTRAN for Linux.
Sector7's expertise in VMS to Linux migrations ensured that the real-time functionality and performance of the application were preserved in the new environment.
