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.

Backing up the files¶

All file uploads are stored to the files/ directory. You can copy the contents of this directory to another location to easily back it up.

MySQL database¶

The mysqldump command can be used to backup the contents of your MySQL database to a text file. For example:

/usr/bin/mysqldump -u <username> -p<password> <redmine_database> | gzip > /path/to/backup/db/redmine_`date +%y_%m_%d`.gz

SQLite database¶

SQLite databases are all contained in a single file, so you can back them up by copying the file to another location.

PostgreSQL¶

The pg_dump command can be used to backup the contents of a PostgreSQL database to a text file. Here is an example:

/usr/bin/pg_dump -U <username> -Fc --file=redmine.sqlc <redmine_database>

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 - Downloaded release (tar.gz or zip file)¶

1. Uncompress the new program archive in a new directory.

2. Copy your database settings-file config/database.yml into the new config directory.

3. Copy your email settings-file config/email.yml into the new config directory.

4. Copy the RAILS_ROOT/files directory content into your new installation.

5. Copy the folders of your installed plugins into new installation directory

6. Run the following command from your Redmine root directory:

rake config/initializers/session_store.rb

If you're using a newer version of Redmine, the above file will no longer exist. On these versions, run

rake generate_session_store

This will generate a file (config/initializers/session_store.rb) with a random secret used to secure session data.

7. 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:

svn update

2. If you are upgrading from an older version to 0.8.7+ or from the trunk version of Redmine to r2493 or above, you must generate a secret for cookie store. See the note at the bottom about generating a session_store.

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:

rake db:migrate RAILS_ENV=production 

If you have installed any plugins, you should also run their database migrations. If you are upgrading from Redmine 0.8.x as part of this migration, you need to upgrade the plugin migrations first:

rake db:migrate:upgrade_plugin_migrations RAILS_ENV=production 

rake db:migrate_plugins RAILS_ENV=production 

Step 5 - Clean up¶

1. You should clear the cache and the existing sessions:

rake tmp:cache:clear
rake tmp:sessions:clear

2. Restart the application server (e.g. mongrel, thin, passenger)

3. Finally go to "Admin -> Roles & permissions" to check/set permissions for the new features, if any.

Common issues¶

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 session_store.rb¶

An unique session_store.rb file needs to be generated for Redmine for the new cookie based sessions to work. This is required on the trunk version of Redmine at r2493 or above. Just run the following command and Redmine will create one for you:

rake config/initializers/session_store.rb

Note: The code repository for Redmine does not contain the config/initializers/session_store.rb file, it is created by the above rake command. If the above command does not work, make sure you are running Ruby 1.8.7 and have Rails 2.3.5 (see Error about the Rails version below).

Errors about a missing session_store.rb¶

If you see any errors about a missing session_store.rb file, run the command above to create a new one.

Error about the Rails version¶

Also remember that the trunk version of Redmine after r2886 uses Rails 2.3.5, so you will need to upgrade your Ruby on Rails gem:

gem install rails -v=2.3.5

Error about member_roles¶

If you have had a failed upgrade/migration in the past then you may have a member_roles and/or group_users table already created. The db migration noted above will fail. Simply rename the tables by logging into MySQL command line and executing the rename table command:

mysql> rename table member_roles to member_roles_saved
mysql> rename table groups_users to groups_users_saved


Error about "undefined method `add_frozen_gem_path'"¶

If you see this error, check if the directory vendor/rails exists and remove or rename it if it does, it might have an old RoR version.
