migrate

Creates a migrations file or runs migrations from the migrations file.

• Migrate packages and create migrations.json (e.g., nx migrate @nx/workspace@latest)
• Run migrations (e.g., nx migrate --run-migrations=migrations.json). Use flag --if-exists to run migrations only if the migrations file exists.

Install nx globally to invoke the command directly using nx, or use npx nx, yarn nx, or pnpm nx.
