Legacy Modernization

Legacy modernization takes the outdated system and converts, rewrites, and
ports the existing applications to a new language that utilizes different libraries, hosting platforms, and protocols.

Approach of Exafluence on Legacy Modernization includes the following 3 stage process:
1
UNDERSTANDING THE PROBLEM STATEMENT

Given any Legacy software application and its associated code for example that could be Cobol, Java, Python, SQL, ETL code as XML etc., understand & visualize the overall functionality, control flow, data structures and logic of the application using a semi-automated ‘reverse engineering’ process.

We could utilize some of the Natural Language processing (NLP) techniques to summarize, document and understand code components and visualize using a knowledge graph. Scope of analysis is to include Cobol, Java, SQL and ETL code (XML)

2
DESIGN PHASE

Once the existing functionality & code of a legacy application is understood and analysed, we need to map the existing components to new ones.

For example,the change of relational data model to document data model could be a better solution, as it is more relevant for a future-proof modern application.

3
PLATFORM TO INTEGRATE

Create a low code / no code platform that can help in automating (to the extent possible) the conversion of legacy application(s) to modern ones through a ‘forward engineering’ processthat includes creating or making an application with the help of the requirements.
