The documentation below is based on upgrading to Redmine 2.x and higher. You can view a previous version for upgrading to Redmine 1.x here.

Step 1 - Check requirements¶
The first step to upgrading Redmine is to check that you meet the requirements for the version you're about to install.
Step 2 - Backup¶
It is recommended that you backup your database and file uploads. Most upgrades are safe but it never hurts to have a backup just in case.
To understand how to back up your Redmine, please read Backing up and restoring Redmine.
Step 3 - Perform the upgrade¶
Now it's time to perform the actual upgrade. This process is different depending on how you downloaded Redmine. You only need to perform one of the following options.
Option 1 - Download a stable release¶
1. Download the release in either tar.gz or zip format and uncompress the new program archive in a new directory.
Make sure the newly extracted and copied files and directories have the correct owner and group set, so that the user/group running your application server can actually access the files.
Also, remember to add write permissions to the
2. Copy your database settings-file
config/database.yml into the new
config directory. If you're running Redmine >= 1.4 with mysql and ruby1.9, change the database adapter to `mysql2`.
3a. Copy your base configuration settings-file
config/configuration.yml into the new
3b. Or, if upgrading from version older than 1.2.0, copy your email settings from your
config/email.yml into the new
config/configuration.yml file that can be created by copying the available
4. Copy the
files directory content into your new installation (this directory contains all your uploaded files).
5. Copy the folders of your custom plugins from your
plugins directory (or
vendor/plugins directory if upgrading from a 1.x version) into new installation
plugins directory. Make sure that you copy only plugins that are were not initially bundled with your previous Redmine setup.
6. Install the required gems by running:
bundle config set --local without 'development test' bundle install
Only the gems that are needed by the adapters you've specified in your database configuration file are actually installed (eg. if your config/database.yml uses the 'mysql2' adapter, then only the mysql2 gem will be installed). Don't forget to re-run `bundle install` when you change config/database.yml for using other database adapters.
If you need to load some gems that are not required by Redmine core (eg. fcgi), you can create a file named Gemfile.local at the root of your redmine directory. It will be loaded automatically when running `bundle install`.
7. Run the following command from your new Redmine root directory:If you're upgrading from Redmine 2.x or below, remove the following file if it exists:
Then generate a new secret by running the following command under the application directory:
bundle exec rake generate_secret_token
Alternatively, you can store this secret in config/secrets.yml:
8. Check for any themes that you may have installed in the
public/themes directory. You can copy them over but checking for updated version is ideal.
VERY IMPORTANT: do NOT overwrite
config/settings.yml with the old one.
Option 2 - Upgrading from a SVN checkout¶
1. Go to the Redmine root directory and run the following command:
2. Install the required gems by running the following command:
Step 4 - Update the database¶
This step is the one that could change the contents of your database. Go to your new redmine directory, then migrate your database:
bundle exec rake db:migrate RAILS_ENV=production
If you have installed any plugins, you should also run their database migrations:
bundle exec rake redmine:plugins:migrate RAILS_ENV=production
Step 5 - Clean up¶
1. Clear the cache:
bundle exec rake tmp:cache:clear RAILS_ENV=production
2. Restart the application server (e.g. puma, thin, passenger)
3. Finally go to "Admin -> Roles & permissions" to check/set permissions for the new features, if any.
Errors with repository management¶
There were several new features added to the reposman.rb file, make sure you have a group specified if you're having issues ( --group=groupnamehere). Also, make sure you follow the instructions here again if you only copied your Redmine.pm, and update your Apache configuration as the recommended configuration has changed.
Generating a new
Before 2.0.0, a
session_store.rb file needed to be generated in Redmine's
config directory for the cookie based sessions to work.
Starting from 2.0.0, the
session_store.rb file should not exist. Instead, the following command will generate the
bundle exec rake generate_secret_token
Note: The code repository for Redmine does not contain the config/initializers/secret_token.rb file, it is created by the above rake command.
