Services began to adopt JSON because it was a lightweight and efficient alternative to XML. However, even though JSON became the new standard, old services were still in use and being maintained.Rewriting a system from scratch is not easy, and it might not even be necessary.

Using the Strangler Fig with Mobile Apps (martinfowler.com)
Incremental replacement of a legacy mobile application is a challenging concept to articulate and execute. However, we believe by making the investment in the pre-requisites of legacy modernization, it is posible to yield benefits in the long term. This article explores the Strangler Fig pattern and how it can be applied to mobile applications.
