The core stays the system of record. The upgrade is when the boundaries get drawn.
FLEXCUBE, OBPM, OBB and OBCL upgraded as one estate — with explicit interfaces, a rehearsed cutover and the same team on support afterwards.
Customers, accounts, contracts, positions and the GL stay in the core. Retained customizations are rebuilt as non-invasive extensions so future patches don't break them.

Indicative only. The fixed-scope discovery replaces this with a register-based estimate.
Five stages, evidence at every gate
Select a stage to see what is produced and what the bank signs off.
Current-estate assessment, FLEXCUBE configuration review and reverse engineering of the customization layer: inventory every object, trace its dependencies and EOD impact, then classify it — standardize, reconfigure, re-home to a component, rebuild as an upgrade-safe extension, or retire.
