It is recommended that you create an archive version of your questionnaire when editing and developing a questionnaire, which can be done in the 'EDIT' - 'Archive' - 'Questionnaire archive' tab.
By clicking on the 'Create archive’, a list of versions from the date of creation of the archival version is generated. You have the option of deleting or activating each of the questionnaire versions.
The questionnaire archive is only available to 2KA and 3KA private package users.
