As Magento 2.3 is out, its Beta version is available for installation. Installing the current Magento version to 2.3* is quite simple through CLI.
Magento in its doc provides the script to upgrade Magento to 2.3 but it doesn’t work out of the box as of now. Please follow all the steps in Magento DOC to upgrade through CLI, use the following script install.
Initially, PHP errors occurred during the Magento 2.3.0-beta8 installation script, which is designed for stable versions. After making the required adjustments, the script successfully installed the beta version without issues.
Change pre_composer_update_2.3.php script to:
#!/usr/bin/php

'SYNOPSIS',
<<<SYNOPSIS
Updates Magento with 2.3 requirements that can't be done by `composer update` or `bin/magento setup:upgrade`.
Run this script after upgrading to PHP 7.1/7.2 and before running `composer update` or `bin/magento setup:upgrade`.
Steps included:
- Require new version of the metapackage
- Update "require-dev" section
- Add "Zend\\Mvc\\Controller\\": "setup/src/Zend/Mvc/Controller/" to composer.json "autoload":"psr-4" section
- Update Magento/Updater if it's installed
- Update name, version, and description fields in the root composer.json
Usage: php -f $_scriptName -- --root='</path/to/magento/root/>' [--composer='</path/to/composer/executable>']
[--edition='<community|enterprise>'] [--repo='<composer_repo_url>'] [--version='<version_constraint>']
[--help]
Required:
--root='</path/to/magento/root/>'
Path to the Magento installation root directory
Optional:
--composer='</path/to/composer/executable>'
Path to the composer executable
- Default: The composer found in the system PATH
--edition='<community|enterprise>'
Target Magento edition for the update. Open Source = 'community', Commerce = 'enterprise'
- Default: The edition currently required in composer.json
--repo='<composer_repo_url>'
The Magento repository url to use to pull the new packages
- Default: The Magento repository configured in composer.json
--version='<version_constraint>'
A composer version constraint for allowable 2.3 packages. Versions other than 2.3 are not handled by this script
See https://getcomposer.org/doc/articles/versions.md#writing-version-constraints for more information.
- Default: The latest 2.3 version available in the Magento repository

In the script, please make sure the Magento Beta version is entered directly, as it was not found.
Also, update the composer.json file to install the Beta version, as the minimum stability was previously set to stable.
