Update Typo3 9.5.27 with Composer to 10.4

Question

I tried updating a Typo3 Website running version 9.5.27 in Composer mode to at least version ^10.4.

I updated the composer.json from

{
    "repositories": [
        { "type": "composer", "url": "https://composer.typo3.org/" }
    ],
    "name": "typo3/cms-base-distribution",
    "description" : "TYPO3 CMS Base Distribution",
    "license": "GPL-2.0-or-later",
    "config": {
        "platform": {
            "php": "7.2"
        }
    },
    "require": {
        "helhum/typo3-console": "^5.5.5",
        "typo3/minimal": "^9.5",
        "typo3/cms-about": "^9.5",
        "typo3/cms-adminpanel": "^9.5",
        "typo3/cms-belog": "^9.5",
        "typo3/cms-beuser": "^9.5",
        "typo3/cms-felogin": "^9.5",
        "typo3/cms-fluid-styled-content": "^9.5",
        "typo3/cms-form": "^9.5",
        "typo3/cms-impexp": "^9.5",
        "typo3/cms-info": "^9.5",
        "typo3/cms-redirects": "^9.5",
        "typo3/cms-reports": "^9.5",
        "typo3/cms-rte-ckeditor": "^9.5",
        "typo3/cms-setup": "^9.5",
        "typo3/cms-seo": "^9.5",
        "typo3/cms-sys-note": "^9.5",
        "typo3/cms-t3editor": "^9.5",
        "typo3/cms-tstemplate": "^9.5",
        "typo3/cms-viewpage": "^9.5"
    },
    "scripts":{
        "typo3-cms-scripts": [
            "typo3cms install:fixfolderstructure",
            "typo3cms install:generatepackagestates"
        ],
        "post-autoload-dump": [
            "@typo3-cms-scripts"
        ]
    }
}

to the 10.4 version

{
    "repositories": [
        { "type": "composer", "url": "https://composer.typo3.org/" }
    ],
    "name": "typo3/cms-base-distribution",
    "description" : "TYPO3 CMS Base Distribution",
    "license": "GPL-2.0-or-later",
    "config": {
        "platform": {
            "php": "7.2"
        }
    },
    "require": {
        "helhum/typo3-console": "^6.0.0@beta",
        "typo3/cms-about": "^10.4",
        "typo3/cms-backend": "^10.4",
        "typo3/cms-belog": "^10.4",
        "typo3/cms-beuser": "^10.4",
        "typo3/cms-core": "^10.4",
        "typo3/cms-dashboard": "^10.4",
        "typo3/cms-extbase": "^10.4",
        "typo3/cms-extensionmanager": "^10.4",
        "typo3/cms-felogin": "^10.4",
        "typo3/cms-filelist": "^10.4",
        "typo3/cms-fluid": "^10.4",
        "typo3/cms-fluid-styled-content": "^10.4",
        "typo3/cms-form": "^10.4",
        "typo3/cms-frontend": "^10.4",
        "typo3/cms-impexp": "^10.4",
        "typo3/cms-info": "^10.4",
        "typo3/cms-install": "^10.4",
        "typo3/cms-recordlist": "^10.4",
        "typo3/cms-rte-ckeditor": "^10.4",
        "typo3/cms-seo": "^10.4",
        "typo3/cms-setup": "^10.4",
        "typo3/cms-sys-note": "^10.4",
        "typo3/cms-t3editor": "^10.4",
        "typo3/cms-tstemplate": "^10.4",
        "typo3/cms-viewpage": "^10.4"
        
    },
    "scripts":{
        "typo3-cms-scripts": [
            "typo3cms install:fixfolderstructure",
            "typo3cms install:generatepackagestates"
        ],
        "post-autoload-dump": [
            "@typo3-cms-scripts"
        ]
    }
}

After that I ran a composer updateand everything went fine. Now when I try to login it tells me that im missing tables in my database. I obviously forgot to update the database aswell, but where do I do that? I tried following this documentation.

Answer 1

When updating TYPO3 to a new major version, you need to run the Upgrade Wizards and Database Analyzer in the install tool. These will convert data/files and create/alter/remove database tables and fields as needed. You should also check the other steps in that documentation.
