Documented steps
Add a packageManager field to the root package.json, e.g. "packageManager": "pnpm@11.10.0" — current pnpm reads this pin itself (Corepack is no longer part of the documented flow).
Inside a project with a pnpm pin, pnpm self-update only updates the pinned version in package.json to the resolved one; it does not install pnpm globally.
Outside a project (or when the pin is ignored), pnpm self-update installs the resolved version globally and links it into PNPM_HOME as the active binary.
Resolve by major, tag, or exact version: pnpm self-update 11, pnpm self-update next-12, pnpm self-update 11.10.0.
Control what happens on a version mismatch with the pmOnFail setting (download | ignore | warn | error) — in v11 this replaces managePackageManagerVersions / packageManagerStrict / packageManagerStrictVersion.

Known gotchas
pnpm 11 requires Node.js >= 22 (and ships as pure ESM). pnpm 12 — currently a release candidate installed via pnpm self-update next-12 (available since v11.10.0) — is a native Rust binary that needs no Node.js at runtime.
Since v11.18.0, self-update deliberately ignores project-level .npmrc / pnpm-workspace.yaml settings so a malicious repo config cannot redirect where pnpm is downloaded from.
In v11, useNodeVersion is replaced by devEngines.runtime in the root package.json (see https://pnpm.io/migration).
