Download as PPTX, PDF1 like1,192 views
The document outlines the enterprise modernization agenda, emphasizing the transition from IMS to DB2 and its associated technical benefits. It provides case studies showcasing challenges faced by organizations, including data latency, and illustrates the advantages of transparent data migration solutions, particularly for a global communications supplier. The document also discusses the cost implications of remaining on outdated systems and presents a technical overview of the migration process.

- 5. 5 Many Organizations Still Rely on IMS… Why? Some may still be on IMS through choice Some may be in IMS because they don’t believe they have a choice Intimate knowledge of the applications has often moved on or retired Rewriting or replacing is deemed too risky Lack of applications knowledge Unknown cost and timescale Maybe a previously failed re-write project in the past? For most organizations it’s easier to stay put…. BUT!
- 6. Limited flexibility - hard to react to changing business needs Restricted capabilities for dynamic and ad hoc access Inconsistent operational data - corporate z/OS standard is DB2, but some critical application data still in IMS Duplication of tools, and the skills and effort to support them On-going software licensing costs for IMS DB and IMS tools Cost of retaining/acquiring IMS skills for future upgrades 6 The Real Cost of Staying in IMS The cost and risk associated with your IMS applications will continue to increase every year
- 7. No changes to application programs. IMS programs execute in exactly the same as before but the data is in DB2 No IMS data propagation required Easily change & support different DB2 design models depending on dynamic access needs PLUS: Option to eliminate all IMS databases once data is migrated Eliminate IMS database tools 7 A Better Approach: Transparent Data Migration
