Changing Apple ID and iCloud account without losing data?
I had to create a new Apple ID in order to move from sharing accounts with my parents because I just got a new phone and I want to switch everything over to my own information. I want to back up all my data on my old phone on iCloud to move over to the new one but now I am worried about deleting the iCloud account on this phone because I don't want to lose my data. I don't want to lose photos, contacts, apps, and most importantly text messages I have some important one I'd like to keep. So my question is will my text messages and all other data stay if I am completely changing both my Apple ID & i Cloud account?
