vercel upgrade command supports package manager aware upgrades

Introduced 2026-01-12 · score 0.98

HOW TO USE IT

When upgrading Vercel CLI and you need to inspect the package-manager command first, run `vercel upgrade --dry-run`; review the proposed command, then run `vercel upgrade` to apply it. Use `--json` instead of `--dry-run` for machine-readable upgrade information; it also implies dry-run behavior.

WHY THIS HELPS

Upgrade the Vercel CLI while checking the proposed package manager operation before applying it.

REQUIREMENTS AND LIMITATIONS

• Version: 50.3.0
• --dry-run: Show the upgrade command without executing it.
• --json: Output upgrade information as JSON; implies `--dry-run`.
• Prerequisite: Vercel CLI must be installed so `vercel upgrade` is available.
• The update prompt is interactive-terminal-only.
