The need for migration of applications or databases in the enterprise arises from changes in business demands or technology challenges either to improve operational efficiency or to manage risk. Many companies today are straddled with the challenge of ensuring that investments in legacy systems do not get locked in proprietary and outdated technologies while migrating to newer systems. The need is to preserve established business rules and practices in the old system at the same time managing valuable human resources locked in maintaining legacy systems.

While options such as rewriting or buying new products exist, migration leverages the business model and the features of the application and can be done in a cost-effective manner.

Why migrate legacy applications

• Maintenance problem, complex architecture, difficult to deploy
  
• Technology obsolete, difficult to find resources
  
• Scalability problems
  
• Business logic mix-up
  
• Integration problem with other systems
  
• Difficult to upgrade the system for new user requirements

Why migrate legacy applications to .Net

• Distributed system
  
• Smart client with win form as well as thin client with web form
  
• Ease of development
  
• Ease of deployment
  
• Xml web services
  
• Richness of the .Net framework

Opus One TECH has a number of years of .Net application migration experience on multiple platforms. As part of our objective to provide an effective enterprise evolution strategy, we help our customers in identifying the right roadmap and strategy to migrate legacy systems at lower costs and leverage the benefits of recent platforms like Microsoft’s .Net to reduce time to market and maximize productivity.

Our .Net application migration services include

• Assessment services to help you decide to stay, port, build, or buy
  
• Strategy services to select the target environment and plan your migration
  
• Implementation and support services

Our .Net migration programs include

• Migration of applications in the same platform
  
• Migration of applications across platforms
  
• Migration of databases, data servers

Opus One TECH’s .Net application migration services enables companies to migrate existing applications currently running on older hardware to modern hardware and software platforms. Opus One TECH provides turn-key .Net application migration services at competitive prices through its development center located in Richardson, Texas.

Clients are able to achieve significant operational cost savings through proven business processes, functionality and data. The new platform, as a result of Opus One TECH’s proven .Net application migration services will be scalable to further application enhancements.

A typical project is split into a fixed-price .Net migration evaluation phase and a .Net migration execution phase:

.Net Migration Evaluation: The existing application is analyzed, the migration project implementation is planned in detail and the effort is calculated. The outcome is a detailed migration analysis document; a project plan and a fixed price quote for the implementation.

.Net Migration Execution: The migration project is implemented as planned and for the quoted fixed price. The project is completed after a thorough acceptance test

Opus One TECH has also performed a number of "like-for-like" migrations from one platform to another. Apart from providing Data Migration services, we also specialize in migrating underlying program codes and forms. Opus One TECH has worked extensively in migrating popular RDBMS products like DB2/Informix, Oracle 7.x/8.x/9.x, and Sybase. Opus One TECH can help in migrating solutions to a transactional SQL backend (such as Microsoft SQL Server or Oracle) with a browser-based user interface, or move the data store to a more powerful backend database and use FileMaker Pro, Access or even VB to create client access to the data.

Platform migration projects usually cover the following aspects:

• Turn-key solutions, including on-site delivery and overall project management
  
• Feasibility analysis
  
• Flexible and professional operating system migrations with application re-engineering where needed
  
• Optimal solution development, including evaluation of alternatives and risk analysis
  
• Conversion of data structures and migration of data
  
• Replacement of transaction processing monitors and non-standard screen forms handling systems
  
• Development of specific tools such as command language interpreters and file access emulators

Programming Language Migration Existing applications represent a significant investment, and a code migration is more economical and faster than a rewrite when upgrading to a new system environment. Manual source code conversion is too risky and expensive, particularly for large and mission-critical projects. To be a leader in low cost and high quality turn-key migration projects, Opus One TECH has developed standardized processes to convert existing application code while leaving the functionality unchanged. The programming language conversion service is available as part of a complete migration project or as a separate contract. Various levels of refinement are provided for different project needs, each at a low fixed price under full warranty:

• Pure language substitution
  
• Language conversion with code clean-up
  
• Language conversion with redesign

Opus One TECH executes and delivers projects on Mainframe technologies and legacy systems for customers including enhancements and up gradations of the existing projects, migration to different platforms and maintenance and support services for such projects.
