How to upgrade magento to 2.1.0-rc1 via composer?

Question

I need to upgrade version of my magento base inside store. All the vendors I'm getting via composer and git contains only my /app/code and /web/composer.json. Current version is 2.0.7 and needed version is 2.1.0-rc1. What can I change inside composer.json to get this version?

Answer 1

Ok, so here's what I would try:

First disable the cache

php bin/magento cache:disable

Then run:

composer require magento/product-community-edition 2.1.0-rc1 --no-update
composer update

Upgrade the DB schema:

 php bin/magento setup:upgrade

Re enable the cache:

php bin/magento cache:enable

You can find more details about the upgrade process in the official documentation here: http://devdocs.magento.com/guides/v2.0/release-notes/ReleaseNotes2.1_RC1CE.html#binstall-using-composerb

Answer 2

Adding to Raphael's answer, I believe the correct composer directive is

composer require magento/project-community-edition 2.1.0-rc1 --no-update

Answer 3

Download patch ( please view official magento page for details where to download ),
Apply patch

composer require magento/product-community-edition 2.1.0 --no-update
composer update

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:flush
php bin/magento indexer:reindex

Enjoy coding!
