Porting Services

Targeted Services: Software ports are not something most companies engage in on a regular basis. Porting applications is an area where engaging outside resources with specialized skills makes good business sense. Migration Specialties provides expertise and experience targeted specifically at porting OpenVMS and Tru64 UNIX applications. Engaging our services to plan and implement a port saves your business time and money.

OpenVMS and Tru64 UNIX ports to a virtual system are generally straight-forward. In most cases, they involve no software changes. They require proper configuration of the virtual hardware, knowledgeable transfer of the operating system, careful transfer of the application data, the adequate testing of the ported system. Ports to virtual VAX and Alpha systems can often be completed in under one week.

Porting OpenVMS applications between VAX, Alpha, and Integrity hardware can also be a straightforward process. If the O/S and layered products on all platforms are at the same revision level, then the port should be a simple matter of transferring and recompiling source code, transferring data, and testing. However, even an ideal port needs to be planned and tested. If your OpenVMS systems are running older versions of the O/S and/or application software, then the porting process becomes more complex.

Software ports require evaluation, planning, implementation, and testing. Migration Specialties provides a full spectrum of in-house hardware, software, and expertise covering OpenVMS and Tru64 UNIX porting needs."
