When setting up your new device, Apple has made things really simple with Quick Start.
With Quick Start, you can set up your new device using the information on your current device — and it’s very simple. Just turn on your new device and place is near your current device. A screen will appear on your current device that will take you through prompts to set up your new device. For complete instructions, visit: https://support.apple.com/en-us/HT210216
Even if you choose to use Quick Start, I still recommend that you backup your data before getting rid of your old device. I also recommend using File Sharing to copy the myArmsCache databases to your computer, just in case you run into any issues. See more details below:
Backup your Data
One option is to use iCloud to backup your data. There are a number of steps you need to follow to make sure myArmsCache is included in your iCloud Backup. You’ll need to make sure you follow the instructions exactly.

File Sharing (also known as iTunes File Sharing)
In addition to backing up your data (or if you don’t want to backup your data), I recommend using File Sharing to keep a copy of the databases on your computer.
It is an additional safeguard that can help to prevent you from losing your data when getting a new device or if something goes wrong with your current device and you can’t restore from backup.
Also, if you want to have your data on more than one device, you can simply copy the databases to that device.
File Sharing Instructions:
The instructions for File Sharing differ slightly depending on what operating system you are using on your computer.

If you’re using macOS Catalina or later, you can use Finder to share files between your computer and your devices. Here is a link to instructions from Apple: https://support.apple.com/en-us/HT210598
*** WARNING *** do not attempt to edit or modify the database files on your computer; doing so could cause serious issues and corrupt the data.
