Limit subscriptions but enable up/downgrades

[gabermeszaros]

Hi there,

First of all, thank you for the plugin. :) Secondly, I have a store with 3 different types of subscriptions each with a monthly and yearly option. Because these are relatively different products we have them separately (and not as variable).

Is there an option that limits the active subscriptions per user to one but lets the user buy another subscription instead of their current one? In this case, users could upgrade or downgrade but have only one subscription at any given time.

Thank you very much for your help in advance.

Best regards,
Gabor
