We have a client running Kerio Mail Server who is in the process of merging with another organization, and it has been decided that they will be migrating their Kerio users to the other organization's Exchange 2007 server. This leaves us with the task of exporting users' Kerio Mailboxes to pst files to import into Exchange 2007. Aside from resetting all the Kerio users' passwords (which is not an option) and manually logging into each user's Outlook and exporting their entire mailboxes to PSTs, is their any tools available that we can run centrally to do this (via an automated process or something?). We don't want to have end users doing this themselves, and we need to accomplish the cut-over all at once after hours... We have about 20 Kerio users with 60GB of mail to migrate.

I would suggest minimum two people each with a dedicated "import PC", a weekend, a gigabit lan connection and a lot of coffee / pizza... The 20 users is not so bad but 60gb will take a while.

I do not know of any apps that will do it but you could look at creating the kerio / Exchange accounts all in advance on a couple of suitable "import" PC's (Just create a whole bunch of profiles called Kerio-User and Exhcnage-User). The when it comes to it you only have to download whats changed in the kerio mailbox since you set the accounts up, export to PST and log in as the user on exchange to import.

Good luck.

Yeah - I didn't find any tools, so I ended up changing everyone's Kerio account to use internal authentication and set everyone's password to password (not for AD, just Kerio), redirected the inbound SMTP proxy to Exchange, then RDP'd into 14 of the desktops as myself (plus 1 session on the XenApp server), created new Kerio mail profiles and exported the entire mailboxes to PSTs housed locally on each PC. While the exports were running, I ran the following Exchange Management Console command for each mailbox:

Add-MailboxPermission "mailbox to grant the rights to" -AccessRights FullAccess -user "Domain Admins"

When the exports finished, I created new Exchange profiles and imported the PSTs. Finally, we use Scriptlogic Desktop Authority for configuring the users' environment at logon, and it has an Exchange profile creator/updater in it. I set it to delete all existing mail profiles for each user on login, and to create a new one for Exchange on their next login.

All total, the job took about 4 hours on Friday evening (from the time I changed authentication until I started a backup job on Exchange after the migration and shut down my VPN connection). Not bad considering I was sitting over 1200 miles away from the client site in my home office when I did it (oh - and no coffee or pizza, but I may have found a beer in the fridge).

Nice! A bit more elegant than the Pizza / Coffee solution lol.
