Following the instructions here, I transferred most of my email from my old
firstname.lastname@example.org account to a custom domain managed by Google.
In my new Gmail account, POP3 is setup to pull from my old Gmail account. In my old Gmail account, forwarding is setup to forward new mail to my new Gmail account.
Do I need both? Is one better than the other?
Also, how do I transfer email in my old Gmail Drafts folder to my new Gmail Drafts folder?
