我有一个Laravel 8.x项目，已经在PHP 7.4上运行了几年了，现在我想开始计划将Laravel升级到v9.x和v10.x。在升级Laravel之前，我想我会暂时将服务器升级到PHP 8.1，因为我不着急。
不包括使用与PHP 7.4相同的配置配置PHP 8.1所涉及的服务器工作，就我而言，在Laravel方面，这只是运行composer update的问题，对吗？
下面是项目composer.json文件的一个片段以供参考：

"require": {
        "php": "^7.3|^8.0",
        "backpack/crud": "^5.0",
        "calebporzio/parental": "^0.11.0",
        "doctrine/dbal": "^2.8",
        "fideloper/proxy": "^4.4",
        "fruitcake/laravel-cors": "^2.0",
        "google/apiclient": "^2.12",
        "intervention/image": "^2.5",
        "laravel/cashier": "^13.0",
        "laravel/framework": "^8.0",
        "laravel/passport": "^10.0",
        "laravel/tinker": "^2.5",
        "predis/predis": "^1.1",
        "rollbar/rollbar-laravel": "^7.0",
        "spatie/laravel-http-logger": "^1.7",
        "mixpanel/mixpanel-php" : "2.*"
    },
    "require-dev": {
        "backpack/generators": "^3.0",
        "facade/ignition": "^2.5",
        "fzaninotto/faker": "^1.9",
        "mockery/mockery": "^1.4",
        "nunomaduro/collision": "^5.0",
        "phpunit/phpunit": "^9.3"
    }

P/S：我还打算用php-redis替换predis，用fakerphp/faker替换fzaninotto/faker。
