Topic: How to Migrate Enterprise-Level Java/Spring Boot Application Painlessly from Old Versions to New Ones

Application migration from old Java/Spring versions to new ones could seem as an easy. But everything drastically changes when you have to migrate ecosystem consisting of tens or even hundreds components and microservices. Vast scale, unique architecture and wide range of dependencies excludes ability to apply simple and one-size-fits-all solution. However, there are constant points based on which you can build an approach and reach success even in the difficult cases.

I am going to share a practical experience how our R&D team successfully done a system migration from old Java and Spring Boot to a new versions, the system which consists of more than 400 components and microservices. I will talk about obvious and not at all obvious problems we had to face. Likewise about successful along with failed solutions and what tools, approaches were used.
