Migrating Zimbra to Another server

[fjimenez21]

I have a ZImbra server v. ZCS 5.0 in HP Proliant 350 G3 with 1 GB memory, this server was updated from 4.5.7 two months ago. My OS is Centos 5.0 and I have 490 users. In this moment I have setting other server HP Proliant 350 G4 and 3 Gb ram; this server have more capacity in HD and processor.
In the last week I backup and restored my old server in this new server according to wiki Open Source Edition Backup Procedure - Zimbra :: Wiki
and http://www.zimbra.com/blog/archives/...er_server.html

but mta in postfix cant send any email. Obviously, my short experience in this case is not good. and returned to my old server for this week. Today I want to migrate but I need your suggest and the best recommendation.
Regards.

Yes, my new server is setting similar with my old server, and dns server, ip and hostname is similar.

When you attempt again we need some logs or error messages to work from (log file list).

When in doubt, follow the blog article.

If you somehow don't keep permissions in your backup process (rsync -avHK should though) then afterwards:

su - root
chown -R zimbra:zimbra /opt/zimbra/*
cd /opt/zimbra/libexec/
./zmfixperms
