Legacy Migration – Migration of Legacy Systems

A legacy migration process represents a massive, long term business investment. As the name Legacy Migration Solutions implies, the focus for nearly two decades centers exclusively on the design and creation of reengineering tools for the purpose of transforming complete legacy applications. From platform migration to language and database transformation, the available suite of legacy migration tools in the market has solved reengineering challenges for a wide spectrum of platform and operating system environments. 

Several options exist for legacy migration systems, defined as any monolithic information system that is too difficult and expensive to modify to meet new and constantly changing business requirements. Legacy Migration Techniques range from quick fixes such as screen scraping and legacy wrapping to permanent, but more complex, solutions such as automated legacy migration or replacing the system with a packaged product.

 

Debate on Legacy Migration can be traced more than a decade, when reengineering experts argued whether it was best to migrate a large, mission critical information system piecemeal or all at once. Legacy Migration can create a functionally equivalent information system based on modern software techniques and hardware. But the high risk of failure associated with any large software project lessens the chances of success.

 

Many legacy migration projects failed because of the lack of mature automated legacy migration tools to ease the complexity and technical challenges. That started to change in the mid 1990s with the availability of legacy migration tools from some companies with advanced technology. These legacy migration tools not only convert legacy code into modern languages, but, in doing so, also provide access to an array of commercially available components that provide sophisticated functionality and reduce development costs.

 

The Internet is often the driving force behind Legacy Migration today. The Web can save an organization time and money by delivering to customers and partners business processes and information locked within a legacy system. The approach used in accessing back office functionality will depend on how much of the system needs to be Internet enabled. Another option of Legacy Migration is replacing an older information system with modern. 

 

Legacy Migration is one of the most difficult challenges we face today. Constant technological change often weakens the business value of legacy systems, which have been developed over the years through huge investments. IT people struggle with the problem of migrating these systems while keeping their functionality intact. Despite their obsolescence, legacy systems continue to provide a competitive advantage through supporting unique business processes and containing invaluable knowledge and historical data.

Application Assessment – App Audit Process

In the current business climate, it is essential that IT professionals understand the process of Application Assessment – Application Audit, coz of the new and more complex challenges faced by them. An application audit is a specific audit of one application. For example, an audit of an excel spreadsheet with embedded macros used to analyze data and generate reports could be considered an Application Audit. Application Audits can also pertain to a business process that heavily relies on various information technology systems. Application audits can also be of a more technical nature like of a PBX or a single data warehouse.

 

Application Assessment is customized to your specific needs. Application Assessment helps your organization manage its risks, prioritize assets, resources, and identify issues before they result in down time. Application Audit is a broader range Application Assessment. Application Audit is an application assessment whose scope focuses on a narrow but business critical processes or application.

 

In the application audit, the central question is that of personnel and system access. With this in mind, there are several access-related factors that auditors must be aware of during an application audit. A further step in the application audit involves looking at the principles underlying these access levels. 

 

Application Assessment (Application Auditing) process involves a number of integrated tools and engineering tasks in order to identify, de-couple, assess, disseminate and understand an application in its most granular form. There are several tools available to automate the following steps in Application Assessment process: Source Audit, Data Audit, Architecture Audit, Complexity Audit, Business Audit and Performance Audit.
