We recommend a full backup before the installation. In the most common case, just delete the folder with the previous version redmine/plugins/redmine_favorite_projects and copy the new version to the same folder redmine/plugins/redmine_favorite_projects
Note: All data will be saved after updates from previous versions.
Here are common steps for Favorite Projects plugin upgrade (all commands should be executed from Redmine app root folder ex. /var/www/redmine, that folder contains config.ru file)
Delete the previous version
cd /var/www/redmine rm -fr plugins/redmine_favorite_projects
Copy and unarchive new version
cp redmine_favorite_projects-[version]-light.zip plugins/ cd plugins unzip redmine_favorite_projects-[version]-light.zip
Install required gems
cd /var/www/redmine bundle install
Migrate plugin tables
bundle exec rake redmine:plugins NAME=redmine_favorite_projects RAILS_ENV=production
Restart Redmine app
For Phusion Passenger just touch restart.txt file
touch tmp/restart.txt
