Keeping up to date in a bespoke software development world
summary
Argues that upgrading often hinges on framework and plugin compatibility not feature desire: Spring/Spring Security and Hibernate churn causes the hardest migrations, dependency hell and duplicate-jars cause NoSuchMethodError incidents, and missed upgrade windows can force multi‑year delays (one case waits ~3 years). Recommends integration tests over unit tests, small step migrations, and containerizing dev stacks with Docker Compose then moving to Kubernetes for QA/rolling updates; typical upgrades take one to two work days plus a few subtle fixes.
