I changed email hosting from GoDaddy (IMAP) to Google Apps (IMAP). The account is now live meaning all MX records have populated. All of the messages that were on GoDaddy account are stored in my Thunderbird. What is the best way to get those messages into my Google Apps account? Its the same email address, can I just change the server information in Thunderbird? I was thinking if I did it might wipe out all of the emails and folders I currently have. Thanks in advance.
