Porting email from old Apple device to a new one

[#1]

Apologies if this has been covered before but I found nothing on a quick look.

I am aware that PN does not allow new customers for email.

I need to transfer email to a new device. Backing up the old device and restoring to the new one will be a nightmare but what about PN email?

Can I even set up a new device?

If I can, do I set up the same account data in the new Mail app then shut down the old device?

Do I shut down the old device Mail app account first then set up the new one? This seems logical but my concern is that this will cause my attempt to set up the new device to be treated as a new customer therefore losing all past and future emails.

All info gratefully received. TIA.

@Mardler Transferring your data from one Apple device to another is simple. Are these phones or tablets, and which versions are they?

Is your PN email  via webmail or a client?

@Mardler it won't!. The email system doesn't identify what device is being used to access email.

"Transferring mail" needs semantic clarification.

If the Apple device accessed the mailbox using IMAP, then "transfer" is simply a matter of adding the mail account to the new device as an IMAP client.

If the Apple device accessed the mailbox using POP3 then it is entirely a different ball game ... and I'm unsure where to start other than doing Google searches.  The email history will be stored somewhere on the old device (certainly that is where sent items will be) ... but Apple devices (iPhone / iPad) do not have an accessible filing system as understood on a PC / MAC.

Also, if your account has the email facility, its functionality is not impeded by the service not being offered to new users.  You can still add new email addresses as mailboxes, aliases or redirects.

Thanks all.

I had been mulling this over and had come to the conclusion that setting up the account on the new device with current IMAP settings should work. Your replies seem to agree.

The only problem I foresee is momentarily having two accounts.

@Mardler if you're using IMAP , then that's not a problem. All the email is stored on the server and each device configured for the same email account will see exactly the same content. For example I have at least 5 devices accessing the same mail accounts.
