A tech’s guide OF LEGACY SYSTEM MIGRATION INTO Z/TPF
WHY THERE IS A REQUIREMENT FOR LEGACY SYSTEM MIGRATION OF TPF INTO Z/TPF? • • • • •
It enables large scale memory blocks Allows smooth assimilation of TPF into the SOA model Provides high volume of the transaction management Processing efficiency is higher Boosts 40,000 direct access storage devices
WHAT ARE THE REQUIREMENTS OF Z/TPF? The approach is crucial while performing TPF’s legacy system migration into the z/TPF environment: • Planning plays a crucial role in transitioning TPF into z/TPF: • Identification of future hardware and software tools • Understanding the new requirements after interface modifications • Preparing a suitable environment for the new system • Ensure proper manual checks • Provide the complete tool kit and remediation for z-code • Proper onshore, offshore, and SME reviews for z-code • Cross-check business logic with regression testing
HOW to go about SUCCESSFULLY IMPLEMENTING THE WORKING OF Z/TPF? • Follow a checklist consisting of small activities vital for code’s • • • •
processing Manual checking of issues occurring while processing Ensure checking of unchecked, complex natured files at third-stage Ensure a regression testing and analysis report for verification Provide guidelines for PRE environment
How to Handle These Barriers of Migration? • • • •
Requires rigorous monitoring of the dumps in the production system Fixing the issues should be treated as a first concern Milestones with specified timelines should be set To keep the business logic safe, ensure: • Setting a dedicated team for analysis • A three-level review testing phase
