It discusses the limits of backward compatibility and the need for clear communication when breaking changes occur. The post closes with a call for community participation—through code, documentation, testing, or mentorship—and thanks key contributors including Sai Boorlagadda, Arnout Engelen, and Leon Finker. ## Full article daily.dev links to this article rather than hosting it.

I'm so happy to see this news here! **@agustinbarrientos** · 0 upvotes > Which broken 1.x API caused the first incompatible dependency during the 2.0 migration? A published mapping plus one CI upgrade fixture would help other teams verify the same path. **@jliter85** · 0 upvotes > I like the point about breaking a huge modernization project into smaller, deliberate steps. Trying to update everything at once sounds like a good way to create a mess really fast. It’s also pretty cool seeing a project that was almost finished come back and get another life because people were willing to put the work into it. ## Similar posts on daily.dev - [Apache Geode 2.0, Part II: Rebuilding a Distributed System for the Modern Java Era](https://daily.dev/posts/apache-geode-2-0-part-ii-rebuilding-a-distributed-system-for-the-modern-java-era-lugevnhys) · The Apache Software Foundation Blog · 12 upvotes · 0 comments - [Apache Geode 2.0: Revival, Reinvention, and the Road Ahead](https://daily.dev/posts/apache-geode-2-0-revival-reinvention-and-the-road-ahead-w0uon6rtj) · The Apache Software Foundation Blog · 4 upvotes · 0 comments - [ASF Project Spotlight: Apache Geode](https://daily.dev/posts/asf-project-spotlight-apache-geode-jvvspzsut) · The Apache Software Foundation Blog · 5 upvotes · 0 comments - [Grails Is Back: Inside the Apache Software Foundation Migration](https://daily.dev/posts/grails-is-back-inside-the-apache-software-foundation-migration-d9fo36rdy) · Foojay.io · 1 upvotes · 0 comments - [The Challenges of Evolving Your Service: Api Versioning](https://daily.dev/posts/the-challenges-of-evolving-your-service-api-versioning-zfwjay9ps) · ITNEXT · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#java](https://daily.dev/tags/java) [View this post on daily.dev](https://daily.dev/posts/apache-geode-2-0-part-iii-lessons-learned-and-the-path-forward-oskenjwst) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Apache Geode 2.0, Part III: Lessons Learned and the Path Forward","url":"https://daily.dev/posts/apache-geode-2-0-part-iii-lessons-learned-and-the-path-forward-oskenjwst","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/apache-geode-2-0-part-iii-lessons-learned-and-the-path-forward-oskenjwst"},"datePublished":"2026-08-18T16:04:54.564Z","dateModified":"2026-09-14T06:43:24.064Z","description":"This final installment reflects on lessons from modernizing Apache Geode to version 2.0, emphasizing ordered dependency upgrades, early test modernization, and...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1a4f6f54e6f36696733b97de18844433?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1a4f6f54e6f36696733b97de18844433?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"The Apache Software Foundation Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The Apache Software Foundation Blog","logo":"https://media.daily.dev/image/upload/s--SQsDxMlv--/f_auto/v1721999281/logos/apache","url":"https://daily.dev/sources/apache"},"commentCount":3,"discussionUrl":"https://daily.dev/posts/apache-geode-2-0-part-iii-lessons-learned-and-the-path-forward-oskenjwst","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":16},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":3}],"keywords":"open-source,java","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The Apache Software Foundation Blog","item":"https://daily.dev/sources/apache"},{"@type":"ListItem","position":3,"name":"Apache Geode 2.0, Part III: Lessons Learned and the Path Forward"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/apache-geode-2-0-part-iii-lessons-learned-and-the-path-forward-oskenjwst","comment":[{"@type":"Comment","text":"What a great project!
