The Co-existence Blueprint: Bridging Legacy and Innovation in Banking

As ASEAN’s banking sector rapidly transforms, financial institutions must modernise while safeguarding the stability and compliance of their core systems. Developed by FPT and audax, the whitepaper explores coexistence as a sustainable path to digital transformation, retaining legacy cores as systems of record while integrating cloud-native platforms for innovation. Targeted at senior banking and technology leaders, the paper draws on FPT and audax’s proven hybrid-architecture expertise to present practical frameworks for incremental modernization, reduced risk, and faster growth, highlighting the industry’s shift from costly “rip-and-replace” programmes to modular, API-first ecosystems that drive agility, new revenue streams, and collaboration.
