Realize you cannot easily transfer data between accounts, and purchases not at all. Make sure this is something you really need to do. If al you need to do is change the email address then click on the links and read the documents -->

Change your Apple ID - https://support.apple.com/HT202667 - "Follow these steps to change the email address that you use as your Apple ID." Plus special instructions if you want to change your Apple ID to an @icloud.com address. You may also wish to turn off "Find My" before changing information and turn it on again afterward.

"If you try to change your Apple ID to an @icloud.com email address that was created within the last 30 days, you will be asked to try again later.

If you see a message that the email address you want to use isn't available or is already in use, check that you or a family member aren't already using that email address with a different Apple ID. If a family member is using that email address, remove it from their account then try to use it."

"After you change your Apple ID email address or password, you might need to update your sign-in information with any Apple services you're using" Click on this link to read "What to do after [or before] you change your Apple ID email address or password" --> https://support.apple.com/HT204071

- This is particularly important to do if you use the "Find My" feature. Disable Find My before changing your information, change the information, then reactivate it with the new information.

You can transfer some things, but it is cumbersome. Purchases cannot be transferred and since the first ID is to be deleted, anything bought with it won't be available for sharing with Family Sharing.

I'd just like to note that you can't transfer content from one Apple ID to another so, anything you've purchased on the old Apple ID will become inaccessible under the new one.
