Applying a New Apple-ID?

See the instructions below for changing an Apple ID. You will lose no information.

Change your Apple ID  https://support.apple.com/en-us/HT202667Read these two sections very carefully to see what is allowed: If your Apple ID is a third-party email address and How to change your Apple ID if it ends with @icloud.com, @me.com, or @mac.com.

Before changing your Apple ID using a computer, sign out of all Apple services that use your Apple ID. If you are going to use an iPhone, iPad, or iPod, then stay signed in with your Apple ID on only that device. This instruction is taken from the above document under the heading Before you change your Apple ID.

For sign out purposes, see Where can I use my Apple ID? https://support.apple.com/en-us/HT202659 “This list is provided for informational purposes only and is subject to change without notice. It's not intended to include every feature or service that uses Apple ID. Visit the Apple ID support page for more information.”

If you do a name change as posted above, you retain access to all your data and prior purchases. If you create a new Apple ID, you lose access to some of your data and all prior purchases. You can try setting up Family Sharing between the IDs if you want to be able to share purchases made with the IDs.
