Large Scale Summit Upgrade and Consolidation in a Highly Complex Environment
Context
A German Bank had a fragmented and unsupported Summit architecture on an unsupported version of Summit running on outdated hardware with non-strategic database technology.
Previous attempts to upgrade & consolidate failed, due to complexity of the environment and volume of the data (6m live trades, 2,000 active users, more than 150 interfaces).
Business objectives
Consolidate onto a single Summit global front-to-back instance, without any negative impact on the business.
In Scope
8 Summit instances to be collapsed into one.
Front-to-back functionality.
6m live trades: Rates, Credit, EM, FX and Money Markets.
Upgrade from V3.8 to V5.6
Migration from Classic to FT
Migration from Sybase to Oracle
Migration to new batch control software (Control M, from autosys and cron)
Static data reconciliation and harmonisation
Business centres in London, New York, Singapore, Sydney and Tokyo and users in more than 20 locations.
More than 2,000 users
More than 3,000 batch jobs
More than 150 interfaces
Solution
Phi Partners provided all Summit Analysis, Design, Build and Unit Test functions with Architecture consultancy and significant input into the wider programme management function.
We reviewed all possible migration pathways and landed on the single viable phased approach taking into account countless business, technical, financial and procedural variables.
Our technical experts overcame the largest challenge: namely, developing a robust, recoverable process to complete a simultaneous major version upgrade and database technology conversion inside the narrow go-live window afforded by a globally accessed business-critical environment.
Outcomes
Acceptance of all design and technical deliverables, first time
All Phi milestones met, according to agreed timetable and scope
Successful go-live; first 3 phases the largest & most complex.
