I have two existing subscription groups in iTunes connect which is in released state from last 3 years. Now, i want to combine all the subscription items into a single subscription group without impacting the users who has already subscribed.
But, i don't see an option to move these subscription items between groups.
My question here is how could we efficiently combine these subscription items from diffrent group into a single group?
Any help would be appreciated.
I do not think that you can move subscriptions between groups. Subscriptions are connected to the group. Look at the subscription groups as to part of subscriptions. If you need to create new subscription group, you should create new subscriptions.
As solution, you can show in the application only one subscription and handle different subscription as same subscription.
