Composer – aktualizace NETTE

Zdravím a prosím o radu.

Když mám composer:

{
	"name": "nette/sandbox",
	"description": "The sandbox is a pre-packaged Nette Framework project, basic configured structure for your application.",
	"homepage": "https://nette.org",
	"type": "project",
	"license": ["BSD-3-Clause", "GPL-2.0", "GPL-3.0"],
	"authors": [
		{
			"name": "David Grudl",
			"homepage": "https://davidgrudl.com"
		},
		{
			"name": "Nette Community",
			"homepage": "https://nette.org/en/contributors?lang=en"
		}
	],
	"require": {
		"php": ">= 5.3.1",
		"nette/application": "~2.3.6",
		"nette/bootstrap": "~2.3.0",
		"nette/caching": "~2.3.0",
		"nette/database": "~2.3.0",
		"nette/di": "~2.3.0",
		"nette/finder": "~2.3.0",
		"nette/forms": "~2.3.0",
		"nette/http": "~2.3.0",
		"nette/mail": "~2.3.0",
		"nette/robot-loader": "~2.3.0",
		"nette/safe-stream": "~2.3.0",
		"nette/security": "~2.3.0",
		"nette/utils": "~2.3.0",
		"latte/latte": "~2.3.0",
		"tracy/tracy": "~2.3.0",
		"dg/adminer-custom": "~1.6",
		"nextras/forms": "^1.6",
		"ublaboo/datagrid": "^5.0"
	},
	"require-dev": {
		"nette/tester": "~1.3"
	}
}

a chci přejít na poslední NETTE.
Mám nějak odinstalovat ty balíčky a nahradit je „nette/nette“: „~2.4“ nebo jak na to prosím?

Díky!
