Upgrade Instructions 3.0 → 3.1

By using composer, you can update an existing installation to a specific version, without having to create a new project.

See the release notes for a list of breaking changes.

For further information on what changed please take a look at the release notes and the changelog.


As always, before doing substantial changes, make sure you create a backup of the database and files!

cd /installation-root/
# Update the core package dependencies
composer require --no-update "neos/neos:~3.1.0"
composer require --no-update "neos/nodetypes:~3.1.0"

# Update optional package dependencies (if installed)
composer require --no-update "neos/demo:~3.1.0"
composer require --no-update "neos/site-kickstarter:~3.1.0"

If you have development packages in your composer manifest, update them to match as well:

# Update development packages (if installed)
composer require --no-update --dev "neos/buildessentials:4.1.x-dev"

Now do the actual update:

# Update the packages
composer update

# Flush the caches
./flow flow:cache:flush --force

# Run code migrations (as needed for any packages that need to be migrated)
./flow flow:core:migrate --package-key …

# Run database migrations
./flow doctrine:migrate

# Publish resources
./flow resource:publish


You may have some legacy dependencies and configuration entries in your composer manifest. Feel free to check if the following is needed in your setup:

# Remove the following line from composer.json (if present)
"minimum-stability": "dev",
# Remove unneeded dependencies
composer remove --no-update "neos/flow"
composer remove --no-update "doctrine/migrations"

If you run into trouble with Neos content or resources, the following may help: 

# If you experience issues with pages not working, try
./flow node:repair

# If you experience issues with resources, thumbnail or assets, try
./flow resource:clean
./flow media:clearthumbnails
