Hi All,

I need opinions on the best way to handle this migration. I have a customer that has been using mail from Mac OS X Server 10.4 and Now Up To Date and Now Contact for shared address book and calendaring.
They want to combine these functions and make the move to Kerio Mail server, but they do not want to do it all at once. They would like to start populating the Kerio Calendar and training people on the webmail interface before they make the cutover this summer.

Does the following order of operation make sense?

1 - Install Kerio Mail server on the current NUDC (no port conflicts) server now

2 - Populate calendar and train users on interface using http://

--At Cutover Time--

3 - Migrate IMAP information over to Kerio Mail server (how would I do this? Currently the user authenticate with OD credentials, but the kerio server will authenticate with AD credentials - same usernames fortunately )

4 - Finally, move the entire Kerio installation to newly installed Leopard server (called so we would not have to change anything with spam service, firewall, etc) and users would use the URL to access their mail and calendar.

This order seems to be fine. The point is, how are you planning to migrate all the Calendars from your old server to the new KMS ? Do you have something specific in mind ? How many users are you talking about? If you give us more details, we probably will be able to help out.

Regarding the migration of the messages from the old server to the new KMS server ---> You can use one of the open source migration tools or you can probably ask for an IMAP migration tool if Kerio has one. I heard they will release an IMAP migration tool.

Here's the well known open source tool:

Moving the messages is actually quite easy... i just did it last week. I changed the IMAP listening port on Kerio MailServer to 144 long enough to migrate, then was able to use the MoveIMAPMail utility that comes with a competitor's software to migrate over. I made a ZIP of the migration utilities for my own use, but you can download communigate pro, and open the installer package to look for them yourself. No need to install the software.

As for the calendars, that might be more tricky. I haven't used NUD/C since the Mac OS 9 days, so I don't know if it has any sort of export as .ics option or not.. if it does, do that, then setup iCal for each user into Kerio, then import the .ics and iCal does the rest.

That's the best I can offer.
