Translations:Upgrading from a previous version/9/en

Upgrading from version 1.50 or later to any later 2.xx version

• Download the latest version of LimeSurvey
• Backup your files and database (did we already mention that?).
• Replace all the installation directory files
  • Delete all old files in the existing installation directory
  • Upload and unpack the new files of the new version into the same installation directory
  • If your previous version is older than 1.90, copy any customized templates to /upload/templates - you will also need to rename each template directory whose name matches an existing template in /templates
  • Copy your /upload directory back to the old location
  • Double-check the permissions set on the directories (write access to /tmp, /upload, and their subdirectories is required) as described in the installation wiki
  • Open http://<yourdomain>/<yourlimesurveydir>/admin in your browser and follow the instructions (You will find the database data in the old config.php). The existing database will be automatically detected and if necessary, upgraded after confirmation.
• Check if any special manual checks apply as listed below
• Now, clear your browser cache and cookies and you are good to go
