NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

过渡架构（transitional architecture）在替换遗留系统时是一种有用的做法。就像在建筑物建造或翻新过程中可能会建造、重新配置并最终拆除脚手架一样，在遗留系统迁移中也经常会需要临时架构步骤。尽管过渡架构最终会被移除或替换，但它们并不是一种浪费，这是因为过渡架构可以帮助降低风险，并可以将困难问题的解决分解为较小的步骤。这些较小的临时步骤很难构成一个完善的架构，因此避开了使用“大爆炸”方式替换遗留系统的陷阱。需要注意的是，替换结束后要记得移除架构的“脚手架”以避免它在以后成为技术债。
