Hi

I am picking up my new phone tomorrow at the Apple Store and trading in my existing phone.

Is there any advantage to upgrade my existing phone to IOS 13, tonight, before trading it in? Will that shorten the time to set up my new phone?

Thanks

I would advise NO if your phones are on IOS which is jailbreakable. :)

Wouldn't bother. You can set up from an iOS 12 backup just fine tomorrow. It will add to the new feeling 🤣
Are you sure about this because the new iPhones will have 13 and in he past you could not restore from a backup made with an older iOS version from what I remember. I just updated my XS and my wife’s 8 Plus in preparation of going to the Apple store tomorrow morning.

Absolutely, I suspect most will be jumping from iOS 12 on their old device to 13 on their new one. It's the other way around that's the problem (eg, 13.1 beta to 13.0 out of the box)
 

now i see it

If your backup is from an earlier iOS version (iOS 12) than the one installed on your new iPhone, (iOS 13) you won't be able to restore the new iPhone from backup because the new phone isnt allowed to run iOS 12.

So to answer your question; Yes, install iOS 13 on your old iPhone before backing it up so that your new iPhone can use that backup (if you want to do that)

Yes if you want to restore from a back up. Made the mistake before of not updating and I couldn’t restore from an older backup.

my mistake... I think I had a beta version on the old phone which was a newer OS than the new phone.

I would just update it, back it up in iCloud, encrypt a backup on my mac, then turn it in.
That's my theory, too. I'll do an encrypted iTunes backup and an iCloud backup tonight or tomorrow morning and probably take my Mac with me since I expected the store wifi will be j-a-m-m-e-d.

I think it's the other way around. You can restore from a lower version to a higher version, but not from a higher to lower.

not true, it’s the other way around. You can restore a backup from an older version of iOS to a phone running a newer version.

what you couldn’t do is create a backup on iOS 13 and restore that to a phone running iOS 12.

OP, it makes no difference for you either way.

Wait - you can hand old phone in at the store? I wasn’t given that option. Have to wait for a kit to be mailed to me.
