That's cool.

Now, even though I have the network version, can I still use brained's procedure above?

The key issue I have is that the current server has 1GB of space left, so doing backups will be a bit of a problem.... which is why I was hoping there was a migration tool for the Network version.

Yes, the procedure works on both editions.

I understand the space thing.

Another option would be IMAPSYNC, but you'd loose some stuff, like documents. So, we probably should do the tar /opt/zimbra thing.

Lookup how to use rsync
man rsync

You can also just rsync the /opt/zimbra folder to the new server.

it's really up to you, but everything is contained in /opt/zimbra

• Re-run the 4.0.4 install script on the new server
• Start up the 4.0.4 on the new server and make sure it's running properly (LDAP, MySql, message store, etc) Really make sure - you don't want to try to upgrade a broken system
• Shut Zimbra down and then -
• Then run the install script for 4.5.6

OK, re rsync, got any options I should be using. I'm trying:

rsync -Wur --links source dest

should I be adding aything else?

OK.. I'm up to the part where I have re-run the 4.0.4 install and I'm trying to make sure it is running properly.

Well, it is sort of working... outlook can get it, I can get into the web interface, send email and so on.

In the web interface I am having some problems though.

When i look at "some", not all, emails I get:

Is this serious? Is the migration a failure? This is the point I need to know whether to scrap everything I've done so far and try again (although I did everything right I am sure).

I've got to wake up in 5 hours and go explain to the boss where I am up to, it woulda kinda be nice to know what to tell him. I will check here when I wake up.

Try running the zmfixperms script located in /opt/zimbra/libexec

Yup, ran it, didnt do much.

When I first login as a user or click on the message it says 'A network service error has occurred.' with the detail being the above.

OK, ran out of time and had to junk to migration - had to give the users back their email access.

So, what can I try to make this more successful next time?

This will copy the files (to a backup directory) with all permissions:

# rsync backup
rsync -avrlHKpogDt /opt/zimbra/ /data/backup/zimbra

# rsync restore
rsync -avrlHKpogDt /data/backup/zimbra /opt/zimbra

obviously change the backup directory to one of your own. You should also make a note of the zimbra uid & gid on the current server and then make sure it's the same on the new install.

I forgot to add that this type of migration assumes your are using the same IP and hostname on the new server.
