title: Upgrading laravel into 8 I got illuminate/support support?
body: <p>I try to upgrade my laravel 8 as I read here
  <a href="https://laravel.com/docs/9.x/upgrade" rel="nofollow noreferrer">https://laravel.com/docs/9.x/upgrade</a></p>
  <p>But after I applyid some changes in composer.json I got error :</p>
  <pre><code> $ composer update
   Loading composer repositories with package information

   Your requirements could not be resolved to an installable set of packages.
   Problem 1
      - illuminate/support[v5.8.0, ..., 5.8.x-dev] require php ^7.1.3 -&gt; your php version (8.1.2) does not satisfy that requirement.
      - illuminate/support[v6.0.0, ..., v6.19.1] require php ^7.2 -&gt; your php version (8.1.2) does not satisfy that requirement.
      - illuminate/support[v7.0.0, ..., v7.28.4] require php ^7.2.5 -&gt; your php version (8.1.2) does not satisfy that requirement.
      - illuminate/support[v8.0.0, ..., v8.11.2] require php ^7.3 -&gt; your php version (8.1.2) does not satisfy that requirement.
      - Root composer.json requires artesaos/seotools ^0.20.2 -&gt; satisfiable by artesaos/seotools[v0.20.2].

      - artesaos/seotools v0.20.2 requires illuminate/support 5.8.* || ^6.0 || ^7.0 || ^8.0 -&gt; satisfiable by illuminate/support[v5.8.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev].
      - Only one of these can be installed: illuminate/support[v5.8.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev], laravel/framework[v9.0.0-beta.1, ..., 9.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
      - Root composer.json requires laravel/framework ^v9.0 -&gt; satisfiable by laravel/framework[v9.0.0-beta.1, ..., 9.x-dev].
      Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

  <p>How that can be fixed ?</p>
  <p>Thanks!</p>
