Microsoft Foundry details six-phase process for migrating LLM models
Microsoft Foundry has detailed a six-phase process for moving LLM-powered applications between model generations, with model retirement dates now built into the platform lifecycle. The guidance emphasizes that swapping model names can silently change response formatting, schemas, and tool behavior, and that validation and canary rollouts are necessary because offline evaluation can miss production issues. A worked example ends in a deliberate split deployment rather than a clean cutover.
