Legacy Decommissioning Overview
Top 3 Benefits
Of Decommission
Lean and efficient portfolio
Cost Savings by retiring applications
IT asset cleanup to comply with auditing and
statutory norms
Top 3 Reasons
for Decommission
Applications having redundant functionality
Unsupported and unused products
Non compliance of audit and IT
9
Legacy Decommissioning involves retirement
of older and outdated business applications
that are partially or no longer in use.
The benefit of carrying out decommissioning
exercise is to make the portfolio lean and
efficient and while generating some cost
savings by removing unused or non-
performing applications from the portfolio.

Case Study 1 – Mainframe Decommissioning
Customer Business
Function
• One of the largest Blue Players
Business Drivers
• Client wants to sunset the
geographical based system which
serves for GA state customers once
their distinct functionalities have
been moved to a consolidated
system to reduce their IT spending.
Engagement Details
• Duration: 12 Months
• Application Size:
• 500K users
• Handling 60 – 80 K claims per day
• 40 external and 35 internal interfaces
• 4 plex regions & 8 testing regions
• Locations: Columbus, GA and
Chennai (India)
• Technologies: COBOL, VSAM, JCL,
EASYTRIEVE, CICS.
Challenges Faced
• Interdependencies Analysis
• Multiple interfaces with internal
systems within the organization
• Vendor component Analysis
• Supporting application Analysis
Syntel Solution
• Provided end to end solution and phase wise approach for sun setting the application, data migration &
archival
• Analyze the dependency to sunset applications effectively with zero impact
• Domain expertise and technical skills in implementing the decommissioning & run off support
• Utilized custom built proprietary tool, Identeon, to understand the dependencies along with Relativity’s
Modernization Workbench for COBOL based systems
• Involved utilities like ARDS SU for critical applications and jobs
Customer Benefits
• Zero impact on other interfaces
• Daily Claims report helps business to clean up the pending
claims
• Application archival was later used to restore the system
when required.
• The team leveraged to provide daily dashboards and
status reports that provided management with a clear and
accurate picture on the projects status
Customer Appreciation
• “Please share a big 'thank you' to your team for being able
to retrieve and calculate this information for the customer.
This just validates the excellent job of 'properly sun setting
an application' and having the necessary information/ skill
sets available to do the manual portion. Thanks again for
coming to our rescue.”

Case Study 2 – Legacy Decommission Sequencing
Customer Business
Function
• World-leading financial services
company
Business Drivers
• Define the legacy elimination
roadmap for 320 legacy applications
from their cash securities portfolio for
controlled elimination of legacy
applications and create self-funding
model for legacy elimination
execution
Engagement Details
• Duration: 3 Months
• Size: 320+ Applications
• 3 (onsite) ( 2 in the US & 1 in UK)
• Locations: London, New York, APAC
• Technologies: COBOL, VSAM,
CICS, DB2, IMS DB, JAVA, VB.
.NET & Proprietary
Challenges Faced
• Understand 320 complex
applications which evolved for more
than thirty years with four different
technology platforms
• Collecting the information on Legal
entities being supported by
applications and analyze the same
with the planned legal entities of the
target platforms to get the legal entity
coverage
• Calculating the effort required and
get the Returns on Investment on
quick wins

• Started with information gathering on 320 applications, through questionnaires, one-on-one discussion
with Application owners, Infrastructure owners and Subject Matter Experts
• Perform Technical Feasibility Analysis, Risk & Criticality Analysis for each application to identify
candidates for near term and long term
• Perform detailed Legal Entity Analysis for analyzing the legal entity coverage by each application
identified for decommissioning and their target application
• Analyze the Benefit & Cost Savings from decommissioning legacy applications
• Validate the findings with stakeholders thru validation workshops to align the approach and strategy with
Business priorities
Customer Benefits
The key benefits of this exercise were manifold, including:
