Do I need to activate premium plugins license keys on prod or staging?

WP Staging Pro license key must be activated on the live site only.

​The same goes for many other plugins. It might be possible to activate a plugin on the staging site and then pushing the staging site but it often requires another “activate license click” within the premium plugin to inform the plugins license server that you activate the plugin on your site.

​Many plugins work without activating the license key at all and the keys are used only for update purposes. So it might be enough if you activate the license keys on the staging site only but this depends on the plugins you use. So there is no generally applicable answer possible.
