I have had a Gmail account for years, and have been using POP to
retrieve my work email as well into the same personal Gmail account.
I recently signed up for Google Apps using my own domain
(work)....although I have not changed the MX records to deliver my
work email to the newly created Google Apps account yet.  My question
is this:

Can I keep the same personal Gmail account and still access my work
email (from Google Apps) without using POP retrieval?  The reason I
want to do this is because I have thousands of emails already stored
and labeled in my Gmail account that I don't want to lose access to.
If this is not possible...how could I import these messages into the
new Google Apps account and then just retrieve my personal Gmail
messages using IMAP?

Hope this makes sense...it sounds confusing to me even though I am
writing it :)

Thanks!
