You have a new iPhone or iPad—congratulations! When transferring your data to the new device, you have four options: Quick Start, an iCloud backup, iMazing Backup/Transfer or a Mac backup. All will work, but they don’t quite provide the same end result (particularly if you didn’t encrypt your Mac backup). Our advice—backed by this post from Apple expert John Gruber—is to try Quick Start first because it transfers everything directly from your old device to your new one, maintaining app logins in most cases and allowing you to transfer your Apple Watch pairing. It may seem like it’s taking a long time before you can use the device, but it’s worth it to avoid logging in to numerous apps and unpairing and repairing your Apple Watch.
We also recommend making sure any security apps, two-factor app and other apps tied to a specific device work, before erasing your old iPhone/iPad.
