While it is tempting to simply move all of your email from your Carleton Gmail account to, for example, your personal Gmail account, we suggest that you consider archiving your Carleton email instead. One of the main reasons for this is that there is no elegant method for transferring email between two different systems. The methods below will work, though they will not transfer the labels that you have created in your Carleton account.
Archiving email has the advantage that you are simply downloading and storing the email for future reference, in case you need to refer back to it in the future. It helps to keep your old Carleton email separate from your current (or new) email, in a searchable location for those times that you need to refer back to it.
