Round 111

Legacy Migration Strategy

Our core enterprise software platform is built on a 15-year-old monolithic architecture that is slowing feature velocity and increasing infrastructure costs. Sales demand modern UI/UX and API integrations, while Engineering warns of mounting technical debt. We have a fixed budget for the next four quarters and must decide how to bridge the gap between maintaining current revenue and modernizing for future growth without halting all new product development.
