How to prepare for a major version upgrade

We first recommend creating a new application with version 6 installed.

Custom survey themes

All custom survey themes (this includes extended themes) will be uninstalled and the options configured will be reset to the default.

Upgrade Strategy:

Export the survey theme from the old application
Import into the new application
Check what changes are required
Implement your changes
Export your customized surveytheme from the new application
After upgrading your old application, import the new survey theme, and you are done!

All custom admin themes will be uninstalled and the new default will be used.

Upgrade strategy:

Copy the existing admin theme from the old application to the new application [insert link to admin theme documentation]
Check what changes are required
Implement your changes
After upgrading your old application, copy the new admin theme into the upgraded application, and you are done!

Custom question themes will still be active, but will need to be checked for compatibility in your new version.

Upgrade strategy:

try to upload your question theme into the new application
make required changes, so it will be compatible with the new version
after successfully uploading, please check if the question theme is displayed and working as expected.

Custom plugins that do not match the current version cannot be activated or installed, but will still be active after the upgrade.

Upgrade Strategy:

Check if the plugin can be installed on the new version.
Update the plugin or contact the plugin author to update the plugin.
Manually override the plugin with new files in your application or uninstall the old version and reinstall the new version (all settings will be lost and have to be reapplied)
