Splitting shared Apple ID

While similar to some questions, I think my question has some unique differences.

My family (mult iphones and iPads) with 6 people. We have been sharing a single apple ID as we started before the family plan was available.

Finally time to split out. We are setting up a new iphone 11.

1. I believe that the apps will still be shared as long as the new phone has a new apple ID connected to the family plan. (correct?)

2. But concerned about contacts, calendar, etc. How can I properly get this data over?

One thing I've considered is backing up the current phone, installing as is on the new phone with the shared apple ID - and then changing Apple ID on the new phone - but concerned that will then end up with problems.

Any advice from the community how to handle this?

Solution 1:

1. Apps: All Apps that are eligible for family sharing will be available on a new AppleID that is added to Family Sharing. Keep in mind that In-App purchases are not shared. More detailed info is available in the Apple Support Article.

2. A desktop computer (preferably a Mac) would probably be the easiest way to properly distribute the content. Set up both the new and old AppleID and then use the appropriate Apps to move/copy the calendars/events/contacts/...
