Moving mail from one server to another?

[Visco]

I'm in the process of moving a lot of my clients hosting packages onto my reseller account. I'm fine transferring all the necessary files to the new server, but I'm stuck when it comes to moving over existing mail on the old server to the new one.

Is there a specific location where the emails are stored on the Blacknight's Linux servers?

Was the mail with on linux or windows previously?

The mail is on a Soho Linux package at the moment, and I need to transfer it over to a Reseller Linux server.

I am just looking into this no myself. . . .

Im currently hosting on a linux server, with register 365 I have setup a mail folder here with black night and was looking at the art mail client and seen add pop3 account, I was wondering if i did the following would this work

1.) have website etc over on blacknight
2.) setup a mailbox say info@domain.com
3.) enter pop3 details of the same email using pop3 details of other server
4.) change name servers


would this work? or is this the best way?
