OpenVMS Migration

Move business-critical applications from OpenVMS

We have over 30 years of experience working with organisations to migrate their custom-developed, legacy applications. We offer a comprehensive, tools-based approach and proven expertise, so we can move your legacy applications from OpenVMS  to Linux or Windows with minimal risk. This is done at a fraction of the cost of redeveloping or buying a package, maximising your return on investment for your OpenVMS applications.
Our automated approach successfully transforms your applications, and re-deploys them onto a new server platform. This means you can continue to meet ongoing business challenges, and maintain competitive advantage, using your critical, core applications.

We can take your COBOL, Fortran, Pascal, C or BASIC application, user interface (SMG, FMS or DECForms), DCL command files and associated data (RMS, Rdb or Oracle) to your choice of Unix, Linux or Windows. We can also improve the functionality of your application along the way.

Are you Facing these Challenges?

There are a number of reasons why you may choose to migrate OpenVMS applications to an open systems environment. 
These include:

 Need to secure the future of business-critical applications

Wanting to reduce running costs

Need for better application integration

Standardisation on corporate hardware platform

Minimise dependence on scarce skill sets

End of support for various flavours of OpenVMS

The benefits of migrating your OpenVMS applications


Minimise risk

With our automated tools, proven methodology and 30 years of experience, you can trust our experts to handle this process safely.


React quickly

You will have increased agility with more reliable business intelligence. Modernised applications will enable you to react to market changes, and ensure your organisation stays competitive.


Effective and clear planning

We define timescales and provide costs upfront to ensure that you know what expect from the project.


Minimal business disruption

We partner with you during the whole process to understand your business fully to make sure there is minimal disruption. Our automated tools ensure that your business logic and user interface remain consistent.


Availability of skills

The skills required to manage and develop applications on the VME platform are becoming few and far between, causing them to be expensive. Migrating to a modern environment makes more specialists available to support your technology. Our consultants are highly experienced with migrating a vast range of legacy applications, and will guide you each step of the way.


Don't just move, improve

After a successful migration, improvements can be made to the user interface, systems can be integrated, data can be transformed, and security will be enhanced.

How we Achieve a Successful Migration

We provide a comprehensive tools-based approach to rapidly and successfully move your business critical OpenVMS applications to just about any UNIX, Linux or Windows platform that you want.

  • Whether your programs are written in COBOL, BASIC, FORTRAN, Pascal, ADA or C, our tools provide a conversion path to an open systems compiler
  • Our tools provide full emulation for either FMS or SMG screen management tools. This means no retraining for your users, they can use the system immediately
  • Our data migration tools handle the conversion of the data to the new relational format. Alternatively, you can take your RMS files directly to an equivalent ISAM structure on your target platform
  • The program syntax is either converted to a corresponding open systems version of the language, or in the case of Pascal or BASIC the code is converted to C
  • The solution allows you to take your migration as an opportunity to modernise your database. RMS files and RDB tables can be migrated directly to Oracle or Microsoft SQL Server
  • We provide full support for running your DCL and VMS jobs on the target platform without any conversion. There’s no rewriting to cryptic UNIX scripts or Windows .BAT files. You can run your DCL as is, without changing a line of code!
  • We provide comprehensive runtime support for OpenVMS system service calls, removing the need to rewrite or convert these calls within your application code
  • Minimal risk - We have an automated tools-based approach, proven methodology and over 30 years of experience in successfully delivering these projects
  • Minimal business disruption- Automated tools ensure that business logic and the user interface remain consistent
  • On time and on budget - Our methodology defines each stage of the project and our analysis provides timeframes and costs upfront
  • Increased agility- Our solution provides the ability to react quickly to business changes and new opportunities with reliable business intelligence using critical, core and often bespoke applications

Why Itanium’s imminent demise further increases the risks associated with OpenVMS applications

The OpenVMS operating system was developed back in the 1970s, and it continues to drive numerous mission-critical business systems worldwide. These often custom core applications are invaluable to organisations across industries ranging from nuclear power to international financial services. Large sums of money and decades of time have been invested in these OpenVMS applications to meet very specific needs - but end-of-life is looming large and planning for their future is now a matter of urgency.

What is the true cost of legacy applications on your business?

Many organisations rely on an assortment of legacy systems to keep their business operating. However, this dependence on an ageing infrastructure is becoming ever more expensive. There are plenty of statistics suggesting that maintaining and operating legacy applications consumes anywhere from 60 to 80 per cent of corporate IT budgets – money that could be redirected to digital innovations that would bring greater competitive advantage.
