Transferring from cPanel to Plesk

[DewKnight]

Hello. I work for a small ISP. We have a few domains with a couple hundred email addresses on them. Currently we are moving away from our current server (which uses plesk), to a new one (uses cPanel). We are doing this so that we have more control, better support, and better prices. The problem we have, is when it comes to transferring the accounts, specifically the email accounts. Since we have a couple hundred, doing this by hand is not going to work. I know that in dedicated servers running cPanel, there is an option to transfer from plesk, but only if you have root access. We do not have root access at our old server

Is there any way we can transfer these email addresses? The files and databases I can transfer manually, I just need to get these emails over.

Also, does anybody happen to know what format plesk backups are in? What can I open them with the sift through the files..?

Thank you very much in advance for your help!

edit: We are running plesk 7.5.4 and WHM 10.8.0 cPanel 10.8.1-R113
RedHat Enterprise 4 i686 - WHM X v3.1.0

I highly doubt the current host will give me root access, or any other backup than the normal plesk one.
