I thought GMail had a way to import mail from an old account. Searching a little bit, I found this post from 2009 regarding importing mail into GMail. However, there is no longer an "Accounts and Import" tab in the settings, only "Accounts". There is an option to check mail for another accout via POP3, but I want to grab all the mail from another account, and hopefully be able to label it, too.
Is it possible to import to GMail via IMAP?

It's not supported by Gmail natively. However, since Gmail provides IMAP service itself, you can set up a desktop mail client (e.g. Thunderbird or Outlook) for both old and new accounts, then simply drag and drop all messages to Gmail's inbox.
There are also tools like
imapsyncwhich can copy everything automatically. (Although I am unsure about how they'd handle Gmail's unusual IMAP structure, so I'd probably stick to manual copying.)
