Rewriting and Re-engineering Legacy Environments

Depending on the size and complexity of your legacy application or database, redeveloping/re-engineering your workload may prove the best alternative. Specific languages like Assembler, Fortran, and certain 4GLs are typically rewritten during any move to open systems. A major redevelopment project generally involves designing a completely new system that utilizes a modern architecture to implement the business logic of the legacy application and the data stores of the legacy database system.

Your legacy application is no longer able to meet key business requirements or you are having trouble finding skilled personnel to maintain and update programs in a timely basis. It may be too challenging and time-consuming to integrate your legacy database with new environments. How can you effectively move forward with an IT modernization initiative that effectively leverages new legacy applications and data sets?

Clerity has proven services practices and expertise to assist you with moving legacy language environments such as Natural and COBOL to Java, C, or other new languages to better meet current business needs. Clerity can also help you move legacy data sources such as VSAM and pre-relational systems to modern RDBMS environments.

Before any redevelopment effort is undertaken, adequate documentation describing the functionality of your application either from an end-user or systems perspective needs to be reviewed or developed. Leveraging Universal Test Manager and years of application expertise, Clerity can assist with documenting current functionality if your organization no longer has in-house skills in this area. Clerity can also perform automated discovery and assessment services to gather an inventory of your current IT environment prior to commencing a project to determine the most effective path forward for your organization.
