The migration involved consolidating 24+ GitHub repositories into a mono-repo, updating Maven coordinates to org.apache.grails, implementing reproducible builds with GitHub Actions, and auditing license compliance across 327 artifacts. The effort resulted in 2,000+ commits, 1.2 million lines removed, and release times dropping from 3 weeks to 2 hours. Key lessons include engaging ASF infrastructure early, planning the end state before starting, and aggressively consolidating repositories to reduce maintenance overhead. ## Full article daily.dev links to this article rather than hosting it.
