Move mail from non-Zimbra to Zimbra server

[zcsnewbie]

I've got my Zimbra server up and running, yea!

Every attempt to move mail from my old non-Zimbra server to my new Zimbra server fails miserably.

I've synced Outlook to the old server, done a backup to pst file and tried the Zimbra import tool. The messages come over, but the from part of all the headers is missing.

I've tried syncing Zimbra desktop to the old server, changed the account settings to the new server and syncing again. Only 400 of 4,000 messages sync and then Zimbra desktop refuses to connect to the new server any more.

Tried same as above with Outlook and it will not sync to the Zimbra server.

Any suggestions?

FYI, the instructions in the sticky at the top of this forum are way over my head. No offense whatever to the author, but it assumes so much knowledge of command line Linux and Linux procedures as to make out of reach for a newbie like me.

BTW, my Zimbra is open source on CentOS 5.3.

What is your old mailserver software ? Have a read here for other ways of moving data http://wiki.zimbra.com/index.php?tit...ation_Articles.

Old software is IMail on a Windows 2000 Pro box.

Last night I tried Thunderbird on a Linux box. I got set up for both the old and new accounts. I synced with both to get all the messages from each.

Then I copied the old messages to the new account. However, when I tried to sync again, it stopped part way through and said something about command too big.

Going to look at your suggested link now...

WOW-migration tools are complicated! And beyond me.

Did find other hopefully useful info though. I did the following on the new Zimbra server and will attempt transfer via Thunderbird again.

logged on as root user, then:
su - zimbra
zmprov mcf zimbraMtaMaxMessageSize 50000000

This changes the max imap message size from the default of 10 mb to 50 mb.

I also saw a post that suggests that there is a message size setting on the admin console for Zimbra. I'm going to try and find and upsize that.

You can use imapsync tool to migrate emails from non zimbra server to zimbra server.
