Most complex Summit Upgrade and Consolidation ever delivered
Large Scale Summit Upgrade and Consolidation in a Highly Complex Environment


  • A German Bank had a fragmented and unsupported Summit architecture on an unsupported version of Summit running on outdated hardware with non-strategic database technology.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


  • 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.


  • 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.
