moving all mailboxes from old mailsever (not exchange) to new Exchange 2010 box...

We have a really old mail server that's using a combination of IMAP and POP (although most are IMAP) for the users' mail. I wanted to know if there was a tool like the exchange migration that was just based on protocol that could easily migrate the mailbox data from our server to the new Exchange 2010 box we have.

If that's not possible, what would be the fastest way to get the data from one to the other? We have about 1000 accounts so if it's going to take approximately 30 minutes to migrate the data by hand we would be looking at something like 100 days if we worked on it for 5 hours each day. There must be a better way then that....I'm hoping. :)

Microsoft had developed a free tool called Transporter Suite to migrate accounts from Lotus & POP/IMAP servers, but is not compatible with 2010, only works till 2007 version.

So, you need a 2007 server, install the tool, move all mailboxes and then introduce 2010.
Or purchase third party tools, which are expensive, like Quest.

The only option I see here is to export .pst from outlook and then import it in exchange 2010 using import-mailbox shell command

What is the current Server ?? where the mailboxes reside ...
As above mentioned from 3rd Party mail server to Exchange you can use Transport suite but from legacy Exchange to another there could be other ways ....

Tushar as you say PST and Import ..... PST from Outlook is Unicode and Export and Import can only uunderstand ANSI code .... so it would be an issue and in that scenario we would have to Import via Outlook only .

The current server is an 'end of life' product from many moons ago. Netscape messaging server. The bulk of the clients are IMAP at the moment.

I was trying to think of ways like installing a 2007 Exchange server and then using their import tool they had for that version to get it onto Exchange and then transporting it to 2010, but maybe that's a lot more work than just using the .pst to get it in one hop.

May have found a way...

by putting the Exchange server first in line (in front of the legacy one) then I can set it up as an internal relay domain and then make a send connector to forward the mail on to the old server if there is no mailbox on the Exchange server. That way I can move mailboxes from one to the other at a reasonable pace and it will continue to deliver mail to both until the old one is ready to be decommissioned.
