Un-orthodox Mail migration

Experts,

I have got a very strange migration coming up for a client. Their mailflow is a mess first of all. They get their mailboxes from a reseller provider giving them POP3 mailboxes. That's the first bit. These are then picked up via a POP collector on the onsite server, to which the clients connect to this using manual exchange configuration in outlook 2007.

They are also due 8 new machines from windows XP to Windows 7. This is another bit. Because the mailboxes are POP3 via a POP collector, there is no central location for these emails apart from their local machine. SO with these 8 machines we would have to backup and export these outlook data files (I think they are still saved in pst/ost format) and pull them accross to the new system.

I have done simple 365 migrations and other mail migrations to different platforms but they were all on local/in house exchange servers so there wasn't the risk of losing any emails.

My question is how would you go about this?

The way I would is to swap over the new machines one week pulling across the outlook data files and then coming back the next week to do the mail migration which would be the old fashioned manual migration of change MX records, export PST's to local machines/server, create new mail profile in outlook and import the pst which will then migrate the data into the new mailbox environment. However with the amount of mailboxes and machines they have, I am imaigning this to take the best part of a day at the very least - the email migration that is.

IF anyone has encountered this sort of thing before please let me know or if you have any tips on the face of this, would be much appreciated.

You need to have the info on:

1. Broadband bandwidth of the office

2. The size of PST or OST file

It is a tedious job to complete over the weekend and if you use the PST Capture tool, your life will be a bit easier.
