Changing Subscription Price

[kronnos]

Hi,

I was wondering how do I go about changing the price for a certain subscription. I know how to actually change it but dont know how it will effect members who have already registered and purchased a subscription at an old price. What will happen when the old members subscription expires and its set to auto renew. Will it auto renew at an old price? If it does renew at old price will the system still renew their subscription?

Anyway, can someone tell me the best way to deal with changing the subscription price. Would I have to cancel the subscription of all old members and have them manually renew at new price or what are some of the options?

Thank You!
