The technical context was the transposition of a BNPP application made of ZOS, CA-7, DB2 and CICS and already integrated in its own E-GEN, into a BPCE-IT environment where the tools, standards and operating rules were different.
Its target: an E-GEN specific to BPCE-IT where all components had to be integrated for future changes and deliveries. It was therefore necessary to offer a delivery tool incorporating our norms and standards. A delivery tool was also incorporated for program components arriving by package, in order to offer their management and integration according to adapted circuits and specific integration modalities.
We had several migrations to achieve in one go: the CA-7 scheduler to TWS, tools and utilities around DB2, file transfer products, standards transpositions and alert utilities.
Each migration / transposition required the formatting of multiple information transmitted in a raw way by BNPP, to understand the interactions. It is in this accompaniment that the ISC teams used iCAN and allowed us to study the different evolution needs that we were going to have to deal with. This method made it possible to transpose the CA-7 event-logic into the TWS plan-based scheduling, including dependencies and CA-7 frequencies into TWS planning.
The readability of all this multiple and diverse information has been made possible thanks to iCAN and E-GEN.
Transposition and formatting was done by a real ISC and BPCE-IT migration team who listened to each other, made sensible choices with great reactivity and strength of proposal.
At the end we obtained an E-GEN ready for use, a successful migration, having respected the planning and the planned budgets. An operational system that is robust and gives satisfaction to its users.
