Upgrade Magento from 2.2.6 to 2.3

Question

I am trying to update Magento from version 2.2.6 to 2.3, but i get this errors:

sh-4.2# composer require magento/product-community-edition 2.3.0 --no-update ./composer.json has been updated

sh-4.2# composer update Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.

Problem 1 - The requested package magento/magento-cloud-metapackage could not be found in any version, there may be a typo in the package name.

Potential causes: - A typo in the package name - The package is not available in a stable-enough version according to your minimum-stability setting see https://getcomposer.org/doc/04-schema.md#minimum-stability for more details. - It's a private package and you forgot to add a custom repository to find it

Read https://getcomposer.org/doc/articles/troubleshooting.md for further common problems.

This is the composer version:

sh-4.2# composer --version Composer version 1.7.3 2018-11-01 10:05:06

And this is the composer file.

sh-4.2# more composer.json

Any idea?

Answer 1

Solved using following steps:

Come back to the previous version of composer.json Following instruction from How to Upgrade magento version from 2.2.X to 2.3.0?

In the last step, it says: sjparkinson/static-review is not required in your composer.json and has not been removed fabpot/php-cs-fixer is not required in your composer.json and has not been removed

Run: # composer upgrade

Then you can get errors like this when you try to do:

php bin/magento setup:upgrade ... Class 'Zend\Mvc\Controller\LazyControllerAbstractFactory' not found ...

So you must to edit the composer.json file and modify the autoload section:

"autoload": {
    "psr-4": {
        "Magento\\Framework\\": "lib/internal/Magento/Framework/",
        "Magento\\Setup\\": "setup/src/Magento/Setup/",
        "Magento\\": "app/code/Magento/",
        "Zend\\Mvc\\Controller\\": "setup/src/Zend/Mvc/Controller/"
    },
},

Then run: > composer dumpautoload

And rerun: > php bin/magento setup:upgrade

And it works!

Answer 2

I was facing the same error while upgrading from Magento 2.2.6 Enterprise to Magento 2.3.2 Enterprise. This error occurs most probably due to composer issue. I reinstalled the composer then I executed the below commands and it upgraded my Magento version without any error.

composer require magento/product-enterprise-edition 2.3.2 --no-update

then

composer update
