Antes de empezar...

... lea esta información porque es muy importante:Realice siempre copias de seguridad tanto de los archivos de la aplicación como de la información contenida en la base de datos de la versión de LimeSurvey que esté funcionando en su entorno de producción

Puede hacer esto utilizando una herramienta de administración de bases de datos como por ejemplo,phpMyAdmin, y un administrador de archivos. Si no sabe como llevar a cabo estas operaciones, debería preguntarle a alguien que sepa como realizarlas o utilizar la herramienta ComfortUpdate en su lugar.

La forma fácil (para actualizaciones entre versiones menores)

You can use these instructions if you are doing a minor upgrade  (for example from 2.00 to 2.01)

  • Backup your files and database (did we already mention that?)
  • Delete all the old files/directory except for
    • /application/config/config.php
    • /upload directory (NOTE: If you have any customized templates sitting under /upload/templates, make sure you refresh those with any changes from the new version. The easiest way to check for such changes is to file-compare your old template with the new version of the default template, and 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 brower, 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!

La forma completa (para saltos importantes entre versiones)

Lamentablemente hay varias cosas que hay que tener en cuenta a la hora de llevar a cabo la actualización, por favor, lea las siguientes instrucciones con mucha atención.

Upgrading from version 2.0x to 2.50 or later

  • Please note that the template structure has changed. Your old templates will not be working anymore as the template system is now using responsive templates.

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

  1. Download the latest version of LimeSurvey.
  2. Prepare and backup the old installation
    1. Backup your installation directory files and SQL-based database just in case.
      1. At the command-line level, make a .zip or similar archive of the whole installation directory tree of files. For example in Linux tar cvzf foo.tgz cps100 will tar and zip the whole of the cps100 directory.
      2. Using phpMyAdmin or similar to export all tables; or use the according LimeSurvey Administration button Button-export-sql.png to backup the entire database
    2. Copy your config.php file, modified template directories and the /upload directory separately for quick access later.
  3. Replace all the installation directory files
    1. Delete all old files in the existing installation directory
    2. Upload and unpack the new code version into the same installation directory
    3. 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.
    4. Copy your /upload directory back to the old location
    5. Double check the permissions set on the directories (write access to /tmp, /upload and and their subdirectories is required) as described in Installation
    6. Open http://<yourdomain>/<yourlimesurveydir>/admin in your browser and follow the instructions (you can use the old config.php as reference). The existing database will be automatically detected and , if necessary, upgraded after confirmation.
  4. Check if any special manual checks apply as listed below
  5. Now clear your browser cache and cookies!
  6. You are done (:biggrin:).


Important.png
Attention : If you upgrade from e.g. 1.92, it might be necessary to first upgrade to latest 1.92, then to 2.00, then to 2.06, and then finally to the latest version (e.g. 2.55.x).
Special checks after an upgrade:
  • from any earlier version to 2.xx:
    • The templates have been changed in a lot of places. Please check your customized templates if they are still looking right. If not you will have to edit your templates accordingly (check out the original templates to see what was changed). The upgrade process tries to replace the template.js inclusion by the placeholder {TEMPLATEJS}. If you have javascript issue with your custom template, verify if your template have the placeholder {TEMPLATEJS} in startpage.pstpl.
    • Proper question codes are mandatory, now. After upgrade check the survey logic of all surveys and correct the codes where necessary.
  • from a version earlier than v1.53: When upgrading from a version before v1.53 to the latest version, please check the global user rights of each user. There was a new superadmin right introduced in v1.53 that can give a user the same privilege as the master administration account created during the install. The upgrade script is guessing who to give this right to in the older versions.  As this is not perfect, it should be carefully checked.
  • from any earlier version to v2.06: From 2.05 to 2.06 some unused permissions when editing global permission for 'surveys' were activated. So if a user has any permission besides the 'create' they will be able to apply this additional permission on other surveys then their own. So please check the global permission of admin users that should only be able to see their own surveys and make sure they only have the 'create' permission assigned for 'surveys'.

      2. If your previous version was >= 1.70: Simply replace the new config.php with your backup config.php (as the file format has not changed).

PUF de actualización.

¿Cual es la versión más reciente de LimeSurvey que todavia soporta PHP4?

La última versión de LimeSurvey que ofrece soporte para PHP4 es la versión 1.82+.

Since the data structure and a lot of other things were changed, upgrading from any version previous to v1.50 is NOT possible.  If you have old survey structure files with a *.sql extension the only way to get these into a newer version is to install version 1.50, import the .sql file(s) there, then upgrade that version to the most recent LimeSurvey version. See the also then page Transferring an installation for more details.

Upgrade FAQ

What is the most actual LimeSurvey version that still supports PHP4?

The last release offering PHP4 support was version 1.82+.

Can I upgrade even if I have active surveys?

Yes, you can. Exceptions may be mentioned in the thorough instructions above. We strongly advise to test your surveys after upgrade to check if your design templates still work alright.

What is best way to port LimeSurvey *.sql survey structure files to the latest version?

Install version 1.50, import the file and export the survey structure to the newer .csv format. The latest version still can read the .csv survey structure format.
