Translations:Upgrading from a previous version/27/en
From LimeSurvey Manual
Note: If you have any customized templates in /upload/templates, make sure you 'refresh' those with any changes that come with the new LimeSurvey version. The easiest way to check for such changes is to file-compare your old template with the new version of the default template. If you see any differences other than your customizations, a refresh is needed.
- Copy the new files from the new LimeSurvey package to the existing location.
- Open the admin page in your browser (e.g. https://www.example.com/limesurvey/admin) and check if a database scheme upgrade is necessary.
- After the upgrade: Clear your browser cache and cookies!
