Upgrading from a previous version/nl

Voordat je begint...

... read this because it is very important: Always backup the files and the database of your current installation!

You can do this using a database administration tool like phpMyAdmin and a file manager! If you don't know how to do this, you should not proceed further and ask someone who knows or use the ComfortUpdate instead.

De snelle manier (voor kleine upgrades)

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/folders 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 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!

De grondige manier (voor grote upgrades)

Daar zitten wat meer haken en ogen aan, dus lees het volgende zeer nauwkeurig.

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. You can use [httsp://www.phpmyadmin.net phpMyAdmin] to export all tables or you can use the backup database function of LimeSurvey that is available in the Configuration dialog (under the Advanced tab) to backup the entire database;

Note: Look for the LimeSurvey Administration button to export the database in the older LimeSurvey versions

1. 1. Copy your config.php file, modified template directories, and the /upload directory separately for quick access later.
2. 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 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.
   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 their subdirectories is required) as described in the installation wiki;
   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.
3. Check if any special manual checks apply as listed below;
4. Now, clear your browser cache and cookies! and you are good to go.

  If you upgrade from e.g. 1.92, it might be necessary to upgrade first to the latest 1.92 release, then to 2.00, then to 2.06, and then finally to the latest version (e.g. 2.55.x). Read below for further details.

  De sjabloonstructuur is na versie 2.0 gewijzigd. Oude sjablonen werken niet meer, we gebruiken nu responsieve sjablonen.

Handmatige controles na een upgrade

• upgrades naar 2.xx:
  • Nette vraagcodes zijn nu verplicht. Controleer na de upgrade de logica van alle enquêtes en verbeter indien nodig de vraagcodes.
• upgrades vanaf 1.53 of eerder: controleer of de global user rights van elke gebruiker nog kloppen. Er is een nieuwe superbeheerder gekomen, die een gebruiker dezelfde rechten geeft als diegene die de installatie draait. Het upgradescript probeert te raden wie dit is, maar dit gaat niet altijd goed. Controleer dus de rechten.
• van een oudere versie naar v2.06: Bij de conversie van 2.05 naar 2.06 zijn enkele rechten ten onrechte verleend bij het wijzigen van rechten op enquêtes. Als een gebruiker alleen een enquête mag aanmaken dan kunnen ook rechten als View/read, Update, Delete, Import, Export zijn ingeschakeld. Controleer de rechten van beheerders.

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

1. Download the desired 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 [httsp://www.phpmyadmin.net phpMyAdmin] or similar to export all tables; or using the LimeSurvey Administration button 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. Edit or replace the config.php file:
      1. 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!;
      2. 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);
   4. 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;
   5. Copy your '/upload' directory back to the old location;
   6. 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;
4. Finish the installation/upgrade process:
   1. Once you open the URL to your LimeSurvey administration, the database tables will be updated after confirmation;
   2. Remove or rename the '/admin/install' directory as/if instructed by the installation script;
   3. Check if any special manual checks apply (as listed below).

Handmatige controles na een upgrade

• upgrades naar 1.92 of later: de sjablonen zijn gewijzigd. Als je eigen sjablonen hebt, controleer dan of ze nog goed werken.
• upgrades vanaf 1.53 of eerder: controleer of de global user rights van elke gebruiker nog kloppen. Er is een nieuwe superbeheerder gekomen, die een gebruiker dezelfde rechten geeft als diegene die de installatie draait. Het upgradescript probeert te raden wie dit is, maar dit gaat niet altijd goed. Controleer de rechten dus.div>

Upgrade van een versie voor 1.50 (v1.0 tot v1.44)

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. Check the page related to how an installation can be transferred for more details.

Kan ik een upgrade doen als ik actieve enquêtes heb?

Ja, dat kan. Besef je wel dat de instructies verwijzen naar de handmatige zaken die je moet checken, zeker als je actieve enquêtes hebt met eigen sjablonen.

Wat is de beste manier om LimeSurvey *.sql-enquêtes naar nieuwe versie om te zetten?

Installeer versie 1.50, importeer het bestand en exporteer de enquête naar het nieuwe .csv-formaat. Importeer deze in de nieuwe versie, die kan dat formaat lezen.
