I'm currently running a site with the free version of S2 member with a one month level and one year level. Recently we've been asked to add a six month option. Ideally I'd like the one month to be level 1, six month level 2 and one year level 3, as this obviously makes the most logical sense.
However, if I swap it so that six months is level 2 and one year is level 3, will this demote all my current one year subscribers to six month subscribers?
