This section describes how to upgrade your existing eZ Publish 5.1 installation to version 5.2. Make sure that you have a working backup of the site before you do the actual upgrade, and make sure that the installation you are performing the upgrade on is offline.

Note on Paths

  • /<ezp5-root>/: The root directory where eZ Publish 5 is installed in, examples: "/home/myuser/www/" or "/var/sites/ezpublish/"
  • /<ezp5-root>/ezpublish_legacy/:  Root directory of "Legacy" (aka "Legacy Stack", refers to the eZ Publish 4.x installation which is bundled with eZ Publish 5) normally inside "ezpublish_legacy/", example: "/home/myuser/www/ezpublish_legacy/"

Check for requirements

PHP 5.3.3 and higher is needed. Further information regarding system requirements can be found on Requirements Documentation Page.

Upgrade steps

Step 1: Upgrade the legacy distribution files

The easiest way to upgrade the distribution files is to unpack eZ Publish 5.3 to a separate directory and then copy the directories that contain site-specific files from the existing 5.2 installation into "/<ezp5-root>/". Make sure you copy the following directories:

  • ezpublish_legacy/design/<your designs> (do NOT include built-in designs: admin, base, standard or admin2)
  • ezpublish_legacy/var/<your_var_dir>/storage
  • ezpublish_legacy/var/storage/packages
  • ezpublish_legacy/settings/siteaccess/<your_siteaccesses>
  • ezpublish_legacy/settings/override/*
  • ezpublish_legacy/extension/* (not including the built-in / standalone ones: ezflow, ezjscore, ezoe, ezodf, ezie, ezmultiupload, ezmbpaex, ez_network, ezprestapiprovider, ezscriptmonitor, ezsi, ezfind)
  • src/
  • config.php & config.cluster.php, if applicable
  • ezpublish/config/*

NB: Since writable directories and files have been replaced / copied, their permissions might have changed. You may have to reconfigure webserver user permissions on specific folders as explained in the file permissions chapter of the installation process.

Step 2: upgrade custom legacy extensions

If you are using custom extensions, the sub-directories inside the "extension" directory will also have to be copied from the existing 5.1 installation into "/<ezp5-root>/ezpublish_legacy/extension/". However, make sure that you do not overwrite any extensions that are included in eZ Publish distribution, which currently are (Note: As of eZ Publish 5.2, these extensions have the same version number as eZ Publish):

Note that upgrading the distribution files will overwrite the autoload arrays for extensions. You will need to re-generate the autoload arrays for active extensions later.

Important: If you plan to upgrade your eZ Website Interface, eZ Flow or eZ Demo site package as well, then additional extensions will be updated and the step for re-generate the autoload arrays can be skipped until that is done (links to documentation for upgrading these site packages can be found in the last step of this page).

Step 3: upgrade the database

Import to your database the changes provided in

/<ezp5-root>/ezpublish_legacy/update/database/<mysql|postgresql>/5.3/dbupdate-5.2.0-to-5.3.0.sql

ezpublish.system.<siteAccessName>.database has been removed for defining database settings. You now need to:

  • Define a Doctrine connection

    ezpublish.yml or config.yml

    Pro Tip

    Set your base DB params in your parameters.yml/parameters.yml.dist and refer them here.
    parameters.yml
    ezpublish.yml / config.yml
  • Define one or several repositories

    ezpublish.yml
  • (Optional) Make your SiteAccess config point to the right repository

    ezpublish.yml  Expand source

     

     

    Remove the old connection information

    Note : to benefit from the new configuration, don't forget to remove the old configuration

    Old database access to remove

Step 4: Apply 5.3 configuration changes

YAML files

Since default configuration files have been overwritten during step one, the few additions to those files that were made in 5.2 need to be applied manually to the configuration files.
All of those changes are additions, none of them replaces what you already have.

For most of them, at least one, if not all hierarchy elements (monolog, handler, framework, router...) will already be there. All you have to do is add the missing bits in the existing configuration blocks.

In ezpublish/config/config.yml, you need to add a few default values for the framework

Session name

ezpublish.system.<siteAccessName>.session_name has been deprecated for defining session name. You now need to use ezpublish.system.<siteAccessName>.session.name.

Before:

 

After:

 

In routing.yml, add new login routes and the _ezpublishRestOptionsRoutes route loader:

In ezpublish/config/security.yml, under ezpublish_front firewall, update to fit the following (be sure to remove ezpublish: true):

If you have added anything to parameters.yml, we suggest that you add your custom settings to parameters.yml.dist, so that the composer post-update script handles those, and generates their values correctly.

Templates

In your templates, change your links pointing to /user/login and /user/logout to appropriate login / login_check / logout routes:

Before
After


ezpublish/EzPublishKernel.php

It is not possible to just copy your old EzPublishKernel.php file over from the previous installation, since quite a few changes were made to this file in this release. We suggest that you simply reflect in the new kernel file any changes you made in the previous version.

composer.json

If you had modified composer.json to add your own requirements, you must re-apply those changes to the new version, and run composer update.

Varnish (if applicable)

Anonymous state of a user is not checked through presence of is_logged_in cookie any more. Therefore, when using Varnish, you must change the following in your VCL file:

Before
After

 

Step 5: Regenerate the autoload array for extensions

To regenerate the autoload array, execute the following script from the root of your eZ Publish Legacy directory:

Step 6: Link assets

Assets from the various bundles need to be made available for the webserver through the web/ document root.

The following commands will first symlink eZ Publish 5 assets in "Bundles" and the second will symlink assets (design files like images, scripts and css, and files in var folder)  from eZ Publish Legacy:

Step 7: Clear the caches

Whenever an eZ Publish solution is upgraded, all caches must be cleared in a proper way. This should be done from within a system shell:
Navigate into the new eZ Publish directory.Run the script using the following shell command:cd /<ezp5-root>/ezpublish_legacy/php bin/php/ezcache.php --clear-all --purgePurging ensures that the caches are physically removed. When the "--purge" parameter is not specified, the caches will be expired but not removed.
Note: Sometimes the script is unable to clear all cache files because of restrictive file/directory permission settings. Make sure that all cache files have been cleared by inspecting the contents of the various cache sub-directories within the "var" directory (typically the "var/cache/" and "var/<name_of_siteaccess>/cache/" directories). If there are any cache files left, you need to remove them manually.

Step 8: Upgrade Extensions (site package)

Next, depending on if you originally installed eZ Flow, eZ Webin or eZ Demo site, follow the steps mentioned in the eZ WebineZ Flow or eZ Demo upgrade documentation.
