Modular replatforming is a strategy that involves moving to a new platform leveraging modules or components, and migrating in smaller iterations. This approach helps reduce the risk of disruption, isolate problems that may occur, and help speed the modernization process when the highest priority elements can come online first. As composable (or component-based) architecture is a modern approach, this method of replatforming helps build additional modern elements into the new platform, building greater scalability, agility, and performance.
