With the emergence of cloud-native applications, the question arises how existing, often monolithic, applications can be migrated to this new paradigm. The main migration challenges are the decomposition of an application into fine-grained components and the introduction of cloud computing paradigms. With complex existing applications the migration is difficult. A structured and tool-supported approach would facilitate the migration process, which is why this paper proposes a model-driven engineering based approach. As a basis, this paper derives and presents requirements for such an approach from the literature on the one hand and a migration case study on the other. The requirements are specifically targeted at the necessary models, but also consider the overall approach. The necessities for the realization of a model-driven cloud-native migration approach are shown and remaining challenges are discussed.

随着云原生应用程序的出现，出现了如何将现有的（通常是整体式的）应用程序迁移到这种新范例的问题。主要的迁移挑战是将应用程序分解为细粒度组件以及引入云计算范例。对于复杂的现有应用程序，迁移很困难。结构化和工具支持的方法将促进迁移过程，这就是本文提出基于模型驱动的工程方法的原因。作为基础，本文一方面从文献中推导并提出了这种方法的要求，另一方面从迁移案例研究中得出并提出了这种方法的要求。这些要求专门针对必要的模型，但也考虑了总体方法。展示了实现模型驱动的云原生迁移方法的必要性，并讨论了剩余的挑战。
