Changing Paid Subscrition Amounts
 

I'd like to change the values of my paid subscription amounts but I know if I edit the current values PayPal rebills to the effected accounts will fail.

My question is how do I get around this. Can I create new subscriptions at a new amount and then somehow turn the old amounts off so I only get new subscribers at current rates but PayPal will still fund the old subscriptions?

Thanks*
