This document discusses modernizing legacy IMS applications by migrating data to DB2 without rewriting code. It outlines challenges with maintaining aging IMS environments and skills. DL/2 is presented as a tool to transparently migrate IMS data to DB2, replacing the IMS database stub with no application changes. Benefits include reduced costs, simplified support, and enabling application improvements. Customer examples demonstrate successful IMS to DB2 migrations across industries. Factors for building a business case are reviewed, and migration services from Syncsort are described.

4. • IMS has been a terrific workhorse for decades but the folks who wrote, maintain and support this
platform are heading to retirement
• Re-writing or re-platforming is a significant challenge
• Many projects fail to complete or even get off the ground
• IMS applications are often mission critical, so re-development is a daunting and highly risky undertaking
• Decades of custom business logic is built into these applications – replicating this into new
development is a huge task
What are the challenges to legacy IMS modernization

5. • Bottom line, Status Quo is an easier ask, but at what risk to the organization?
• How will your company replace IMS skills and application programming knowledge over the next few years?
• Outsourcing support and application maintenance to 3rd parties?
• The time to make a low risk move to DB2 is now!!
Making a low risk move to Db2

6. • Transparent migration of the application data to Db2 with no change to application code
• Eliminate on-going DBA and programming support for IMS DB
• Consolidate DBA support to Db2
• Migrate IMS databases to Db2 at your own pace
• Eliminate the high MLC costs of IMS DB and IMS support tools
• No more IMS version upgrades as old versions go out of support by IBM
• DL/2 fully supports IMS DB/DC and IMS CICS environments
Syncsort DL/2 – a low risk migration strategy

7. • DL/2 is a combination of IMS to Db2 migration and mapping tools to migrate IMS segments to Db2 tables
• DL/2 is also the replacement for the IMS Db stub program and acts as the interface between the IMS
applications, which do not change and the migrated IMS data that is now residing in Db2
• DL/2 is a replacement for IMS DB and IMS support tools (IBM, BMC, Compuware etc)
• DL/2 is not replicating data to Db2. DL/2 is replacing IMS DB so that all your production data is now
residing in Db2

18. • Getting buy-in from the DBA team, application stakeholders and senior
management is the key to success
• Review the current status of your IMS support team
• What is the timeline for IMS skills to depart the organization
• What is your backup plan to ensure on-going support of your IMS environment
• Review current IMS DB MLC and IMS Tools licensing costs
• Those costs continue as long as you are still maintaining IMS DB – DL/2 is a one
time perpetual license fee
• Discuss with Application stakeholders the benefits of shifting data to a
relational model in Db2 – Ease of on-going maintenance, easier access to
data and opportunity to modernize applications.
Developing the internal business case

19. • MLC and term license costs
• Cost of IMS Software
• Cost of Software to monitor IMS – BMC, Compuware, CA, IBM
• Cost of Software to Backup, Recover, Reorganize, Validate
• Personnel / Consultants
• Staffing Shortages
• Fewer and fewer developers and DBA’s with IMS Skills
• Potential future reliance on 3rd party support
• Consolidate to one z/OS DBMS
• Simplify DBA support
Factors to consider in ROI

20. • Free of charge DBD and PSB review service
