Translations:Upgrading from a previous version/11/en

Upgrading from version 1.50 or later to any later 1.xx version

• Download the desired 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 code version into the same installation directory
  • Edit or replace the config.php file:
    • If your previous version was < 1.70: Edit the new config.php in order to reflect the changes from the backup config.php file. Do not just overwrite the new config.php with your old one!
    • If your previous version was >= 1.70: Simply replace the new config.php with your backup config.php file (as the file format has not changed)
  • If your previous version was 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 of LimeSurvey (write access to /tmp, /upload, and to their subdirectories is required) as described in the installation wiki
• Finish the installation/upgrade process
  • Once you open the URL to your LimeSurvey administration, the database tables will be updated after confirmation
  • Remove or rename the /admin/install directory as/if instructed by the installation script
  • Check if any special manual checks apply (as listed below)
