Grails has been revitalized under the Apache Software Foundation with Grails 7 as a Top-Level project, but many production applications remain on older, unsupported versions. The post maps out the current Grails and Spring Boot support schedules, explains the 'dependency cliff' risk for teams running Grails 3–6 on Spring Boot 2.x and older Java versions, and outlines practical steps: inventory what you're running via SBOMs, map your EOL exposure, consider commercial extended support as a bridge, and treat upgrades as multi-quarter programmes rather than simple tasks. The author discloses working for HeroDevs, a provider of commercial EOL support for Java ecosystem frameworks.
