The growing complexity of advanced automotive system, consisting of connected, autonomous, and software-defined vehicles, has increased the pace of the transformation of the AUTOSAR framework out of its Classic Platform (CP)-optimised to solutions supporting dynamic, service-oriented architectures (SOA). Although AUTOSAR Classic has been shown to be strong in real-time control systems, it is struggling with the polluted communication, computational scalability and over-the-air (OTA) updates needs of future-generation vehicles. In this paper, a systematic transition framework to facilitate a methodical move between AUTOSAR Classic and AUTOSAR Adaptive will be presented. It has suggested that the legacy Classic components can be mapped to Adaptive service abstractions by the use of standardized middleware interfaces like SOME/IP and DDS, ensuring interoperability and downward compatibility. An execution model is devised that shows the presence of coexistence between Classic ECUs and Adaptive nodes in the form of a single service management layer. Experimental validation using a mixed ECU testbed indicates the following improvements: communication efficiency can improve up to 38% and integration time can reduce by 27% and increase scalability in distributed service deployment. The results point out that the switch to the AUTOSAR Adaptive does not only enhance the flexibility of the system but also preconditions the further automotive innovations, i.e. the use of edge intelligence, cloud integration, and autonomous control systems
