Power Platform connectors cover even older systems (AS\/400, SAP older releases).<\/p><\/details><details><summary>How do we get real-time data from a batch-only legacy system?<\/summary><p class=\"a\">You can't, but you rarely need to. We expose CDC (change data capture) where supported, hourly snapshots where not. Real-time is overrated for 80% of use cases.<\/p><\/details><details><summary>When SHOULD we replace legacy?<\/summary><p class=\"a\">When the cost of NOT replacing exceeds the cost of replacing: knowledge concentration risk, compliance gaps you can't close, vendor end-of-life. Otherwise, abstraction beats replacement.<\/p><\/details><details><summary>How do we avoid the \"modernise once, modernise forever\" trap?<\/summary><p class=\"a\">Build for evolutionary architecture: domain-driven service boundaries, message-based integration, data contracts, continuous deployment.
