I think I did this before, yet can't recall what steps exactly, to make sure 100% of whatever I had in the old device, was kept intact.
Here's the situation:
- The old iPhone is the 7 Plus, the new, 15+, not configured yet.
I asked iTunes to do a local/full (and encrypted) of the 7 PLUS, so all apps, docs, photos, etc. were preserved.
- I have 2 phone numbers, one using regular WhatsApp, the other uses "Business".
What I want:
1) To turn 15+ into the MAIN DEVICE, instead of simply connecting as additional.
2) To connect 7+ as the additional device.
3) Preserve everything from the old phone. For the 2 numbers.
What I did so far:
- Connected the 7 PLUS into my PC and asked iTunes to do a full copy into my SSD;
- Purchased the 50 GB iCloud plan, and asked both numbers (in each WhatsApp) to save into iCloud. Which I did for both, unencrypted.
Once all of that was done, in theory this is what is left:
- a) Wipe the new iPhone 15+ and restore from the local iTunes backup (PC). It's not "restore from iCloud". This will make sure most apps are already logged in the new device, and will retain the former settings.
- b) While I didn't restore anything from iCloud once I used the 15 PLUS for the 1st time (bought recently), logged into the same Apple ID used for the 7 PLUS.
- c) Register the two numbers for each app (Regular and Business) from the new device (15), sending a SMS to both numbers and getting the codes, which will disconnect both from the 7 PLUS. But, since I did step a), everything will be restored, as planned.
- d) Now connect the 7 Plus as the additional device.
I also need to do this:
- Cancel the 50 GB iCloud plan, the idea was instead to save everything from time to time, from both smartphones, as a local iTunes backup. I am not sure if this will become a problem, because if I combine both numbers, even if there's no video saved, they are using more than 5 GB from iCloud (and the free plan is limited to 5 GB).
So, am I missing something? Of course I can't do tests to answer my own questions, because if there's some issue, I may end up losing stuff:
