以下は、Confluence 7.3 にアップグレードする際の重要注意事項です。このリリースの新機能と改善点に関する詳細は、「Confluence 7.3 リリースノート」を参照してください。 


Latest Companion App required

We've made significant changes to how you edit files using Atlassian Companion. When you upgrade to Confluence 7.3, you'll need to make sure your users are also running the latest version of Companion App (1.0.0 or later).  

Earlier versions (0.6.2 and earlier) will not work with Confluence 7.3. 

PostgreSQL 10 のサポート

We've added support for PostgreSQL 10.  If you plan to upgrade, you should upgrade Confluence first, then upgrade your database.  

See pg-upgrade in the PostgreSQL 10 documentation for information on how to upgrade your database. Make sure you back up your database, Confluence installation directory and Confluence home directory before you begin. We strongly recommend you test your changes in a staging environment first. 

After upgrading, we recommend you run ANALYZE. Analyze collects statistics about contents of tables in the database, which the query planner can use to help determine the most efficient execution plans for queries.

There's also a known issue where Confluence won't start with PostgreSQL 10 in Amazon RDS. See  CONFSERVER-59243 - Getting issue details... STATUS  for more information and a workaround. 

Oracle 19c のサポート

We've added support for Oracle 19c.  If you plan to upgrade, you should upgrade Confluence first, then upgrade your database.  

See Database Upgrade Guide in the Oracle 19c documentation for information on how to upgrade your database. Make sure you back up your database, Confluence installation directory and Confluence home directory before you begin. We strongly recommend you test your changes in a staging environment first. 

We've tested Oracle 19c with both the ojdbc8.jar and ojdbc10.jar drivers. 

Emoji support for MySQL

We have added support for utf8mb4 collation for MySQL 5.7 and 8.0. This will allow people to use 4-byte UTF-8 characters in Confluence pages. 

If you're running MySQL 5.7 or 8.0, and you're ready to migrate your database to use utf8mb4 collation, see How to Fix the Collation and Character Set of a MySQL Database. There are some things you need to know before you start:

  • Back up your database first. We also strongly recommend testing the migration in a test site, as migrating the tables may take some time for large databases.
  • If you're running MySQL 5.7, you'll need version 5.7.9 or later. 
  • You'll need to check the character set specified in the my.cnf  or my.ini  file on your MySQL Server. If character_set_server  is not set to utf8mb4, and you can't change this (for example if it is required for a database used by another application) you may need to add the connectionCollation=utf8mb4_bin parameter to your connection URL.  See the Connector/J 8.0 or Connector/J 5.1 documentation for more information. 


    1.Confluence を停止します

    2. Edit the <local-home>/confluence.cfg.xml  file

    3. Update the following line to add the connectionCollation=utf8mb4_bin  parameter to your database connection URL, as in the example below. 

    <property name="hibernate.connection.url">jdbc:mysql://yourhost:3306/confluence?connectionCollation=utf8mb4_bin</property>

    4. Restart Confluence. 

If you're running MySQL 5.6, you will need to upgrade to MySQL 5.7.9 or later, or to 8.0.x, and then migrate your database to utfmb4. If you're not able to upgrade MySQL at this time, you should continue to use utf8. If a 4-byte character is used we'll prompt the user to remove the character before they can save, preventing encoding problems. As Confluence 7.3 is the last version to support MySQL 5.6, it's a good time to start planning your upgrade. 

MySQL health check problem

There is also a known issue with Atlassian Troubleshooting and Support Tools, where some MySQL health checks always fail. We recommend updating the Atlassian Troubleshooting and Support tools plugin to version 1.23.2 or later to avoid this problem. 

Known issues with Inspect Permissions and People who can view

In Confluence 7.3.0 to 7.3.3, the Inspect permissions and People who can view features don't currently take into account some external directory and nested group scenarios. 

See Inspect Permissions returns incorrect information in Confluence 7.3 for a detailed summary of each scenario. 

If your site is impacted by these problems, we suggest you temporarily disable the Inspect Permissions - Gatekeeper system plugin that provides these features until we can provide a fix, to prevent users relying on inaccurate information. See  CONFSERVER-59513 - Getting issue details... STATUS

tip/resting Created with Sketch.


We've improved how the People who can view and Inspect Permissions features work with complex external directory scenarios.

From Confluence 7.3.4 the following scenarios are fully supported:

  • Nested groups 
  • Non-aggregating group membership
  • Disabled directories
  • Disabled user accounts in one, but not all, directories

Note: when you inspect permissions for a specific group, we only report the permissions granted directly to that group. We'll warn you if the group is nested, but won't show permissions granted to any parent groups (you'll have to inspect these separately).  This limitation only applies when you inspect permissions for a group. When you inspect permissions for a user, we display permissions granted by all groups, including parent groups. 

Ultimate Permission Manager app

If you currently use the Meta-Inf Ultimate Permission Manager app, that was acquired by Atlassian, there's some things you need to know before you upgrade. 

  • If you have a Confluence Data Center license, when you upgrade to Confluence 7.3, the Ultimate Permission Manager app will be disabled automatically. This is intentional, so we can give you access to "Inspect permissions" and "People who can view", which are the equivalent features in Confluence Data Center. 
  • If you have a Confluence Server license, when you upgrade to Confluence 7.3, you'll be able to continue to use the Ultimate Permission Manager app until your app license expires. You won't see the new "People who can view" option, but will use the equivalent feature provided by the app. 
  • If you have a Confluence Server license, and your Ultimate Permission Manager app license has expired, we recommend you disable or uninstall the Ultimate Permission Manager app, in order to get access to the "People who can view" feature provided by Confluence Server. 

Disable People who can view

If you currently hide the People directory, or other places where users may be able to see a list of other users, you may not want the People who can view feature. To disable it for your whole site:

  1. Go to <base-url>/admin/plugins/gatekeeper-plugin/global/configuration.action
  2. Deselect the Allow who can view option and save the change. 

Show all pages in the page tree

In the sidebar, we now load a maximum of 200 pages at each level of the page hierarchy. A Show all pages button will appear if there are pages that have not been loaded. This change was made to improve your site performance. 

Disable legacy Edit in Office dark feature

If you previously enabled the legacy Edit in Office functionality, you will need to remove the dark feature flag in order to try our improved Companion app experience. 

To remove the dark feature flag, go to <base-url>/admin/darkfeatures.action and click Remove next to

Enable Edit in Office in the Confluence UI

If you're unable to use Companion app, you can now enable the legacy Edit in Office functionality from the Confluence UI (previously this was done using a dark feature flag).  Go to General Configuration > Office Connector. 

Java 11 now bundled

In this release we've bundled the AdoptOpenJDK 11 JRE. This JRE is used when you install or upgrade Confluence using the installer. If you've installed Confluence manually you can either continue to use Java 8 or switch to Java 11. See Change the Java vendor or version Confluence uses to find out how to switch your Java version.

Some of the Java arguments used in our  / setenv.bat  files are no longer recognised in Java 11. Make sure you apply any customizations manually when you upgrade, don't simply copy over your old setenv file (or existing Java options if you run Confluence as a service). 


Java 11 では、次の引数が置き換えられます。

-XX:-PrintGCDetails -XX:+PrintGCDateStamps -XX:-PrintTenuringDistribution -Xloggc:$LOGBASEABS/logs/gc-`date +%F_%H-%M-%S`.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=2M



We also recommend adding the following new arguments:


IgnoreUnrecognizedVMOptions  means that any unrecognised Java 8 arguments will be ignored. You won't need to remove these manually. 

There are known issues with TLS 1.3, so we recommend TLS 1.1 and 1.2 for now.

詳細な情報については、Java 11 ドキュメントの「Enable Logging with the JVM Unified Logging Framework」を参照してください。 

If you have added additional arguments, you may need to check that these are still available in Java 11, as they may cause errors when you start Confluence. 

Waiting for the next Enterprise release?

Confluence 7.4 will be the next Enterprise release. See the announcement on Atlassian Community.

6.3 以前からのアップグレード

If you are upgrading from Confluence 6.3 or earlier, there's a known issue where spaces do not appear in the space directory. You'll need to reindex your site after upgrading to fix this. 


In this release we have added support for:

  • PostgreSQL 10.
  • Oracle 19c.

Reminder about operating system support

Microsoft ended support for Windows 7 on January 14. You should only install and use Confluence on operating system versions that have active vendor support.
