Faced with a range of challenges, BSK identified an innovative approach that would require resizing their Murex installation. The idea was to extract only the core elements and data to be kept for an optimised target installation.
The project commenced in January 2016, based on a greenfield MXpress target model. The same binary, hardware, operating systems and RDBMS were used, only the data and structures in scope for the downsized banking functions were migrated. The migration scope had been continuously challenged by redundant data and structures, and so the global operating model was stripped down to remove unnecessary entities and portfolios. The overall reporting solution and back-office workflows were redesigned from scratch following MXpress standards, new naming conventions were introduced to ease maintenance and development and most historic workarounds were removed.
Successful delivery required close collaboration between the Excelian team and the bank. As with any migration, there were technical challenges to be managed, but there were also cultural issues to work through arising from the impacts of restructuring on personnel.
In March 2017, following meticulous preparation, with ten full test cycles, the bank could go live and start running the optimised Murex platform.
