Hi Juliani,
I understand you have deployed MATLAB Production Server on Azure using the Azure marketplace reference architecture and want to upgrarde to the newest version in the deployed reference architecture without doing it from scratch.
Unfortunately there is no workaround and you have to follow the instructions as mentioned in https://github.com/mathworks-ref-arch/matlab-production-server-on-azure#deploy-reference-architecture-for-your-release to set up your MATLAB Production Server.
For more information, please refer to https://github.com/mathworks-ref-arch/matlab-production-server-on-azure#faq and https://github.com/mathworks-ref-arch/matlab-production-server-on-azure#architecture-and-resources
Hope this helps.
