Apple family sharing question

Unless this is all inside the same family group when there is a short period when there are two family subscriptions going, you will need to take out an individual subscription to bridge yourself with continuous coverage during the short time when you will not be part of either subscription. If you coverage ends then in the legal documents: Legal - Apple Media Services - Apple you will find, "When your Paid Subscription to any Service ends, you will lose access to any functionality or Content of that Service that requires a Paid Subscription."
