It is recommended that you upgrade your server to the latest version, but as long as you use only features that were available on your version of the server the new survey should work on the older server. Please note that you will not be able to import to the server questionnaires with features introduced in versions that are later than the version of your server.
My Survey Solutions server is not the latest version. Can I still use it with new surveys?
