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:
$ 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
$ sudo installdir/ctlscript.sh start apache
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
