UNIX to Linux Migration

We at Correlated Systems analyze your platform and enable the flexibility of standard virtualization in secure isolated partitions with dedicated resources for improved and predictable application performance while at the same time reducing TCO.

Many critical applications have been deployed in UNIX systems for performance and security reasons; the architecture of the systems provides for partitioning and a degree of security. The users are now looking to reduce the TCO, and address concerns about processors reaching end of life, by moving their applications to Intel X86, primarily with Linux. However, there is a reluctance to move in case security and performance are compromised.

Correlated Systems implements the ideal environment

We provide an ideal target environment. The secure partitions enable predictable performance, the scalability of fabric architecture, secure and isolated partitions and high speed interconnect without compromising the security. The lower hardware and software license costs compared with the UNIX environments reduces the TCO of the system after migration.

We deliver one of the most secure computing environments and has improved the security, predictability and performance of today’s powerful Intel Xeon platform for Linux and Windows operating environments. We offer you the UNIX experience, characteristics and simplicity for a cost effective UNIX replacement.

If you are looking to move to an open platform from your legacy UNIX environment you need the right partner to support this activity. Correlated Systems, through its decades of providing mission-critical systems to some of the largest organizations, understands the risks and concerns of an organization looking to move their critical systems to a new platform.

Our Experts Can Help

Starting with an initial assessment of not only your applications but the infrastructure and service level requirements that are needed to support them, Correlated Systems will then plan the migration process and provide the resources and capabilities to transition your applications to a mission-critical open platform. This whole process is supported by a robust methodology and a specialist application transformation factory designed to drive efficiency, repeatable results and reduce the risk of transition.


Round-the-clock access entails maintaining constant availability, or at the very least, providing systems with minimal interruption. Systems must be robust and reliable to avoid unplanned downtime, and should be upgradable with little or no requirement for planned downtime.


The variable and unpredictable demands imposed by today’s traffic patterns require systems that are highly scalable. It should be possible to provide increased capacity at short notice, without disruption to existing operation. Extra capacity may be required for brief periods to respond to unexpected changes in conditions, or for the longer-term, as a result of a shift in business conditions. An example could be the need for more capacity following a merger with another organisation.


Flexible application development environments are required in order to respond effectively. And delivering new services increasingly requires collaboration with other systems, both within an organisation and externally. Middleware and other features are required to implement such environments.

Support for Multiple Environments

Applications distributed over several co-operating components are now common. The components may operate in different operating system environments, with different database models. It is therefore desirable to support different environments and database models within a secure framework. As an example, the trend towards doing more analytical processing in real time, so that the systems can adjust their responses immediately, leads to a requirement for a variety of processing and database architectures.

We do care about Total Cost of Ownership

An obvious economic factor is the total cost of ownership (TCO) of a system: how does it compare with alternatives? But the goal is not just to minimise the TCO but to do that considering other economic factors and the context within which the system is used. Security, for example, is clearly an economic factor. While there is no cost if there are no security violations, attacks compromising data through theft or corruption can have enormous economic impact, possibly putting the owning organisation out of business.
