There are two main items that need to be addressed when it comes to a member wanting to Upgrade or Downgrade their Subscription from one membership “level” (a.k.a “Product” in DAP) to another.
1) Modifying the actual recurring payments to reflect the new amount
2) Giving them appropriate access as per the upgrade (or downgrade)
So let’s see how both of these are accomplished.
You do need to take some manual action for this. The way to do it is….
Set up automation rules using DAP’s Product Chaining feature, so that if they sign up for one Product (or “level”), they’re automatically removed from another Product (or level).
So if they are currently signed up to your “Gold Membership”, then when they sign up afresh for the “Platinum Membership”, then set up a Product Chaining rule that says, “If member signs up for Platinum Membership, then remove them from Gold Membership”. This is just to make sure that they don’t have access to two products (or “levels”) at the same time.
