What is Legacy Modernization?

“The process of assessing, measuring, prioritizing and executing various techniques designed to upgrade an organizations application portfolio to take advantage of leading edge technical platforms, languages and relational database engines.”

Migration / Conversion

Web-enabling/ SOA / Wrapping

Re-engineering / Re-writing

New Development/ Package Implementation

Any Strategy has to be viewed as a combination of functional and technical modernization

Converts Legacy Green screen to GUI

Screen functions can be wrapped to Java or .NET components

Some would say “lipstick on a pig”, but may be appropriate intermediate step

Platform Migration

Database Migration

Language Migration

Creating a web-based interface for legacy applications

Business logic retained in legacy environment

Screen interface and business logic is extracted from existing system and re-coded in modern technology

Modern technology adoption (off the shelf)

Why?:• Leaves existing application alone• Relatively simple to do• Relatively quick to accomplish• Good choice for applications that have a limited shelf life• Impressive to end users

Why Not?:• Viewed by many as “Lipstick on a pig” approach• Can be a performance nightmare• Doesn’t show demonstrable progress

Why?:• Preserves the application as a valuable business asset• Transfers all the business knowledge to new technology• Complements other LM approaches• Demonstrable progress into new technologies

Why Not?:• Expensive and time consuming• Not a good choice for low-value applications• Requires business unit involvement in testing

Why?:• Leaves existing application alone• Broadens the access to the application• One framework, many applications• Promotes re-use•Leverages existing investment• Use to buy time

Why Not?:• Viewed by many as “Lipstick on a pig” approach• Can have performance implications• Still need to maintain LM technology – puts off problems

Why?:• Allows complete end user control of content• Existing application generally does not meet business needs• Re-write existing functionality AND add new content

Why Not?:• Expensive and time consuming• Very difficult to mine the business rules completely• Requires large investment of IT resources – major initiative

Transfer


Why?:• Traditional SDLC activity• Complete content control• COTS product has high degree of applicability• Transfers can be the quickest route to production and/or compliance

Why Not?:• COTS vendor marriage• Expensive and time consuming• The degree of applicability may not be high enough

Generic LM Program Steps

• Assemble Business & Technical team members• Identify the scope (both in & out)• Gather application data

• User acceptance, criticality, business rule reqm’ts• Complexity, platforms, languages, data stores• General ROI information

• Determine which LM technique you plan to use for each application

• Create mini ROI and feasibility studies• Create Project Charters where applicable• Sequence & launch projects• Monitor & evaluate progress

Success Factors

• The selected solution should be highly automated to minimize manual effort and human error

• The resulting code should be easily maintained with structured code, comments and meaningful data names

• Conversion of non-relational data should include a normalized database design with logical and physical models. The new database should not just copy the non-relational design

• Conversion of non-relational database access should produce efficient, quality code that takes advantage of the new database design

• The selected vendor should have relevant experience with both relational database, platform and language migrations.


April 10, 2008

Why Do Legacy Modernization?

• A safe, risk averse migration to new technologies• Avoidance of proprietary hardware & software costs• End of the mainframe strategies• Change from hierarchical to relational DBMS’s• Release from dependence on legacy vendors• Avoidance of end-of-life support dates• Utilization of newer, more available technical resources• Ability to utilize COTS packages for end user analysis• Relational access allows “web-enabling” to bring the end

user experience to a browser-based user interface • Extension of the ROI for mission critical applications with

their associated complex business rules.
