Go to Surveys > Survey List.
Locate the survey you want to archive in the list.
Expand the Actions menu and then click Archive.
Note: You'll see a message if you still have this survey in a channel.
You can see a list of all archived surveys by toggling on the Show Archived option at the top of the Survey List page.
