We purchased Kerio Mailserver more than 3 weeks ago but got no reply from Kerio on several requests to help us with migrating our mail, addresses, calendars etc. from Exchange Server 2003 to KMS on Leopard Server 10.5.2. Sad

The mail server runs fine on our Leopard Xserve machine, but support from Kerio seems non-existent !!

How do we get our mail, etc. from Exchange Server 2003 (that is in a different domain/network than our new Apple server) to KMS. Preferably without using command line tools, but if that's the way to go we'll give it a try. Our Exchange database is several Gigabytes, and we want to keep the mail dates, flags, etc. intact if possible.

We tried the Kerio migration tool (downloaded from an Italian site as Kerio didn't even bother to reply to our request for a download link) but that stalled after some 55 emails. Maybe a newer version works better, but than Kerio has to reply with a download link!

Because we already use the new KMS server the migrated mails, contacts, events, etc. will have to be merged with the new mails and calendar events.

Does anybody know how to do all this? Any help would be greatly appreciated!

Kind regards,

Hans Vernhout

P.S: Kerio, if you are listening: we are a paying customer looking for help...

Hello Hans,

The way we did this was to use the Exchange migration tool which worked relatively well, bearing in mind we were on exchange 5.5 running on NT.

We had to do a few cleaning up tasks on the exchange database which included removing the journal data from all mailboxes and then running the exchange defrag to compress and re index. We found that this massively reduced the number of emails that failed in the migration process.

From what i can remember you have to run the migration tool on client machine with outlook installed. I would suggest running this tool on a powerfull PC. Also when preferably when no one is using their email account, again this to reduce errors.

Other than using that tool you could export all your mailboxes to PST's and import them. I can imagine on a server with a huge number of users could take a long time.

Hello Hans,

sorry for late reply as it was forwarded to our partner to help you.
Now we will handle it internally.

Basically you have 2 options
- use our migration tool
- import pst files (from local pst to Kerio profile within Outlook)
As you have a few users, importing pst files is not difficult and you can merge with existing data on clients. Both options are time consuming for large mailstores.

Thanks Mark and Jan,

We are trying the pst-files route, as our old and new server are in different domains.
Thing are moving slooowly but steadily; accept for a few emails with empty subject lines and wrong dates everything seems to import fine.

We have only a few users to migrate, so this is not too much work. But you have to be patient for the import to finish all the emails (think workdays. not minutes). As long as the migration succeeds we're happy, but we wonder how big companies transfer their users to a new system.

We still have to figure out if it's possible to bring our contacts, notes, and calendar items into our new system as well (via pst-files or other formats).

To give Kerio some credit where it's due (after my initial complaint): two people from Kerio responded to this thread very swiftly. Brian from technical support mailed me the links to the requested tool and some more information off list.

Thanks for the help. Tips for transferring calendar items and contacts to iCal and Apple Address Book (via Kerio Mailserver syncing under OS X?) are still very much appreciated.

Kind regards,

Hans Vernhout
