2 apple IDs 1 icloud
[wall of text] I’m preparing to backup my device (ipad). ONE device. On this device, I have two apple IDs and 1 icloud account. Backstory as to why... awhile back, my apple id was hacked so in addition to changing my password & applying extra security, I also made a new apple ID out of fear & to make purchases on. But I created an issue since my icloud account is still that old email (I still have the email though rarely use). So, since I still actively use both apple IDs on my device (ie: for downloaded apps old & new), I have to toggle between the two to update those apps.
Note: I don’t use iTunes since I had a residence change & now reside in a town in which we JUST got the internet a couple days ago aside from 4G. So, my computer is inoperable as I haven’t dusted it off since 2012. So, I can’t use iTunes for ANY of these things.
QUESTION: Can I & how do I back up BOTH apple IDs to my ONE iCloud account on my ONE device WITHOUT iTunes (Just ONE iCloud). If I can’t.. would I need to create a separate iCloud for the other apple ID & can I then toggle back & forth from one icloud account to the other to back them up separately on the ONE device?
ALSO, is it possible to change my iCloud account from my old email to my newer email/apple ID (the two I already use on my iPad) to ensure safety when backing up my device & linking a credit card to? I dread using my current (old) iCloud because of hacking concerns. I keep getting alerts that are constantly happening of people from all over the world trying to log onto that older account. They haven’t been successful but knowing that it’s happening every other day is making me massively disturbed. So, I would LOVE to change that older iCloud/apple ID to my newer (safe) apple ID in which I would need to make an iCloud for (?) & change on my device. And will I lose anything by switching?
I hope this makes sense... [/wall of text]
