OpenVMS Application 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, RMS 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

cloud

Minimise risk

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

cloud

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.

cloud

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

  • Our tools provide full emulation for either FMS, SMG or DECforms screen management tools. This means no retraining for your users, they can use the system immediately.
  • Our 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.
  • Our data migration tools handle the conversion of the data to the new relational format. Migrations to relational databases are undertaken by our skilled migration consultants. Alternatively, you can take your RMS files directly to an equivalent ISAM structure on your target platform.
  • 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!
  • There’s no need to worry if your application makes wide use of the many OpenVMS system service calls. Often this can be the most difficult aspect of a VMS migration, but our solution provides comprehensive runtime support for these VMS functions, and removes the need to rewrite or convert these calls within your application code.

Solving the legacy problem once and for all

There is a sense of unease in the UK business climate as we wait to see how Brexit unfolds. The decisions that organisations make in 2018 and 2019 will determine if this period of uncertainty has the potential to turn them into big winners or big losers – there won’t be much in between.
