Upgrade Redmine+Agile

It is strongly recommended that you create a full backup before starting the update process. If you have important data, it is advisable that you create and try to restore a backup to ensure that everything works properly.

Upgrade Redmine and all stack components

The recommended way to upgrade Redmine is to migrate all the data to a fresh Bitnami installation, which runs the updated version of Redmine.

On the original Redmine server, follow the steps below:

• Create a database backup file named bitnami_redmine.sql:

    $ mysqldump -u root -p --databases bitnami_redmine --add-drop-database > bitnami_redmine.sql
  

• Copy Redmine application and plugin files from the directory installdir/apps/redmine/htdocs/files. You can compress the directory in Linux and macOS with the commands below:

    $ tar czf redmine_files.tar.gz -C installdir/apps/redmine/htdocs/files .
    $ tar czf redmine_plugins.tar.gz -C installdir/apps/redmine/htdocs/plugins .
  

Launch a new Redmine server and follow the steps below:

• Stop Apache:

    $ sudo installdir/ctlscript.sh stop apache
  

• Upload the file redmine_files.tar.gz to the new server.

• Restore the database backup:

    $ mysql -u root -p < bitnami_redmine.sql
  

• Copy the Redmine application files to installdir/apps/redmine/htdocs/files. In Linux and macOS, copy redmine_files.tar.gz to the new instance and extract its contents:

    $ sudo tar xzf redmine_files.tar.gz -C installdir/apps/redmine/htdocs/files
  

• Migrate the database to the latest version:

    $ cd installdir/apps/redmine/htdocs/
    $ sudo ruby bin/rake db:migrate RAILS_ENV=production
  

• (Optional) If you had installed plugins in your previous installation, follow these steps:

• Check that the plugins are compatible with the new version.

• Copy the directories from the vendor/plugins directory into the new installation area, in the plugins directory. In Linux and macOS, copy redmine_plugins.tar.gz to the new instance and extract:

       $ sudo tar xzf redmine_plugins.tar.gz -C installdir/apps/redmine/htdocs/plugins
  

• Install the plugins:

       $ ruby bin/rake redmine:plugins RAILS_ENV=production
  

• Clean the cache:

    $ ruby bin/rake tmp:clear
  

• Start Apache:

    $ sudo installdir/ctlscript.sh start apache
  

Troubleshooting upgrades

• If you see the following error, go to your database and remove the specified table and run the migration command again.

    Mysql::Error: Table 'changeset_parents' already exists: CREATE TABLE `changeset_parents` (`changeset_id` int(11) NOT NULL, `parent_id` int(11) NOT NULL) ENGINE=InnoDB
  

  Run these commands:

    $ mysql -u root -p
    mysql> use bitnami_redmine;
    mysql> drop table changeset_parents;
  
    $ cd installdir/apps/redmine/htdocs/
    $ ruby bin/rake db:migrate RAILS_ENV=production
