What does Migration Tool Move?

Hello,

Just curious what the latest version of the Migration tool will move? Does it include

SSL Certificates
Zimbra's settings to use the SSL Certificate
Customized spam assassin rules
Postfix conf files, such as postfix_rbl_override
files in the /opt/zimbra/conf folder

Basically, is everything moved that will allow a new server to operate like the old migrated server?

Thanks,
Daniel
