Node.js 20 LTS Transition Planning Before April 30, 2026 EOL — when and how should I migrate?
Decide whether to move production estates from Node.js 20 directly to 22 or 24 before the Node.js 20 EOL date arrives and downstream platform support windows start closing.

Candidates
Move production estates from Node.js 20 to Node.js 22 first
As of 2026-04-05, Node.js 20 Iron is in Maintenance LTS and reaches end-of-life on 2026-04-30, while Node.js 22 Jod is in Maintenance LTS and is scheduled to reach end-of-life on 2027-04-30. This gives only about one additional year of official support beyond Node.js 20, but it keeps the runtime jump smaller than going straight to 24. Official Node.js 22 release notes highlight features such as requiring synchronous ESM graphs, WebSocket enabled by default, stable watch mode, and fs glob/globSync. The main decision advantage is lower migration surprise if your estate is sensitive to native addons, framework support lag, or broad fleet coordination.
When to choose
Use this when stability and ecosystem maturity matter more than maximum runway, especially for large estates that need a conservative step off Node.js 20 before 2026-04-30. Pick it if you want the smaller semantic jump now and can accept another major-runtime program before 2027-04-30.
Tradeoffs
Pros: smaller leap from Node.js 20, mature LTS line, fewer new platform-level shifts than 24. Cons: short remaining support window, so you are likely signing up for another production runtime migration within roughly 12 months.
Cautions
Check for Node.js 22 migration issues called out in official release notes: import assertions support was dropped, the default stream highWaterMark changed, and older crypto APIs such as createCipher/createDecipher were moved to end-of-life paths. If you ship native modules or custom Windows builds, validate toolchain expectations before rollout.
Skip Node.js 22 and standardize directly on Node.js 24
As of 2026-04-05, Node.js 24 Krypton is in Active LTS, moves to Maintenance on 2026-10-20, and is scheduled to reach end-of-life on 2028-04-30. That gives materially more runway than Node.js 22 and avoids doing two major runtime migrations in close succession. Official Node.js 24 release notes call out npm 11, V8 13.6, AsyncLocalStorage switching to AsyncContextFrame by default, URLPattern becoming global, and the permission flag changing from --experimental-permission to --permission. This is the better default if you want to reset the estate onto the newest long-lived LTS line before Node.js 20 support ends.
When to choose
Use this when you want the longest official support runway and can absorb a broader validation cycle now, especially for platform teams standardizing many services. Pick it if reducing repeated upgrade work is more important than minimizing immediate migration delta.
Tradeoffs
Pros: longest support horizon, current Active LTS status, and one fewer near-term runtime migration program. Cons: bigger behavior and tooling delta from Node.js 20, with more release-note items to audit across builds, tests, and native dependencies.
Cautions
Check official Node.js 24 migration caveats before committing: support for MSVC was removed and ClangCL is required to compile Node.js on Windows, several APIs were deprecated or removed including tls.createSecurePair, url.parse now emits runtime deprecation, SlowBuffer is runtime deprecated, and ARMv7 support was downgraded to experimental. Native addons should be retested because Node.js 24 uses N-API v137 in current LTS builds.
