This time, community contributor Miguel Redondo proactively fixed the netlab SR Linux configuration templates before the blog author noticed, and Roman Dodin released srlconv — a tool that shows exactly what changed between SR Linux software releases and how to fix configurations. The tool works by spinning up two SR Linux containers (via Containerlab) with the same startup config across two releases, saving the resulting configs, and diffing them. Additionally, SR Linux's Python upgrade scripts (srlinux.transform.transformations module) are accessible inside the container image, enabling an even more precise diff of what changed between releases than release notes provide. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I find what changed in the SR Linux configuration data model between two software releases? The srlconv tool (github.com/srl-labs/srlconv) automates this by starting two SR Linux containers via Containerlab with the same startup configuration but different software releases, saving the resulting configs, and diffing them. For an even more precise answer, the Python upgrade scripts inside the SR Linux container image are accessible as the srlinux.transform.transformations module and can be diffed directly between releases. _Network engineers managing SR Linux upgrades track breaking data model changes like these on daily.dev._ ### Are SR Linux container images freely available for lab use? Yes, SR Linux container images are available for hassle-free download, making it trivial to start any SR Linux release locally. This openness is what enables tools like srlconv and Containerlab workflows to spin up arbitrary release pairs for configuration comparison without special vendor access. _Developers building network automation labs find SR Linux tooling news alongside other NOS updates on daily.dev._ ## Similar posts on daily.dev - [netlab 26.09: Syslog, More DNS, Netmiko « ipSpace.net blog](https://daily.dev/posts/netlab-26-09-syslog-more-dns-netmiko-ipspace-net-blog-7hzbp4smq) · ipSpace.net Blog · 0 upvotes · 0 comments - [Yak-Shaving netlab Podman Support « ipSpace.net blog](https://daily.dev/posts/yak-shaving-netlab-podman-support-ipspace-net-blog-s4rwnwdcr) · ipSpace.net Blog · 0 upvotes · 0 comments --- Tags: [#networking](https://daily.dev/tags/networking) [View this post on daily.dev](https://daily.dev/posts/sr-linux-configuration-conversion-tool-ipspace-net-blog-zrloxd7ms) ```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":"SR Linux Configuration Conversion Tool « ipSpace.net blog","url":"https://daily.dev/posts/sr-linux-configuration-conversion-tool-ipspace-net-blog-zrloxd7ms","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/sr-linux-configuration-conversion-tool-ipspace-net-blog-zrloxd7ms"},"datePublished":"2026-08-11T08:52:25.918Z","dateModified":"2026-08-24T07:01:18.417Z","description":"SR Linux release 26.03 again broke its configuration data model, continuing a pattern of annual breaking changes.
