Splitting my Apple ID/iCloud into two
For years, I've had just one Apple ID (and it's a defunct @mac.com address). It's worked fine, but now I want to split my identity... I want to have one Apple ID for iTunes and the App Store, and another one for everything else: contacts, calendar, notes, reminders, iCloud, etc. I'm sharing the iTunes Store one with my daughters, so we can share purchases, but I don't want to share everything else with them.
Seems like I have two options, both requiring a second Apple ID (which I've already created against a different email address).
1) Move everything to the new account, except iTunes.
2) Move iTunes to the new account, leave everything else and change the password.
I'm not sure if option 2 is possible.
Is there an easy way to port all my info from one Apple ID (iCloud stuff) to another? Most of what I've seen involves exporting and importing, one thing at a time.
Any other thoughts on how I might accomplish this? Maybe there's a third option I haven't considered.
Thanks!
