Zimbra 4.5.6 to 5.0.10 upgrade notes

Things I needed to do for Zimbra to work – 4.5.6 to 5.0.10 upgrade.

1) Mysql root/user passwords need to match what’s in /opt/zimbra/conf/localconfig.xml. I played around with mine and managed to screw this up.
2) Since I changed the hostname, ldap wouldn’t start. To fix this, I had to rebuild the SSL certificates. You can do this here: http://wiki.zimbra.com/index.php?title=SSL_Certificate_Problems – I had some trouble following directions – note the version numbers – they’re important. 🙂
3) Make sure that is in zimbraMtaMyNetworks. Ref: http://wiki.zimbra.com/index.php?title=ZimbraMtaMyNetworks – if not, you won’t be able to send mail out – it will say relaying denied.
