OPPORTUNITY ANALYSIS FOR LEGACY
SYSTEMS MODERNIZATION - 3.1.4 COMPLETELY SUCCESSFUL MODERNIZATION
OF VAX BASIC TO J2EE -
[Dec 10, 2004]
The pilot
modernization process was completed and 100%
s"uccessful in porting the EOSS ACC system.
Using automated tools, the code for the business logic was
transformed from VAX-BASIC into J2EE while preserving the
original functionality. As a part of this process the “As
Is” and “To Be” system architecture was mapped.
This showed a reduction in redundant and dead code. Subject
Matter Experts (SME) at NSWCCD tested the modernized EOSS ACC
system extensively and found it to retain all critical
functionality of the mission critical system. The modernized
version is now in use."

Business System Transformation
A
Case Study

|
ROI 2.47:1
|
|
The Naval Network Warfare Command
(NETWARCOM) required modernization of a Navy legacy information
system .The Software Revolution,
Inc(TSRI) performed an automated
transformation of the legacy software into J2EE/Java. TSRI also
made several design adaptations to meet the Navy's architectural
and net-centric requirements.

To some degree, the government's efforts to
reduce legacy systems has focused on Commercial Off The Shelf
(COTS) replacements. Automated conversion of legacy code into
modern object oriented languages has primarily been a solution
for one-of-a-kind systems. However, this trend could be about to
reverse itself. Case studies like the one above continue to
demonstrate the quality and ROI to be gained from automated
transformational technology. Meanwhile, portfolios of COTS
products have not proven to reduce redundancy, nor improve
interoperability. And managers have found that COTS solutions
merely trade mainframe hardware dependency for vendor software
dependency. It seems evident that automated modernization of
existing systems will become a more frequent modernization
solution.
