I have a mail server on Centos with Postfix 2.4.5 mysql smtp-auth
amavisd-new policyd postfixadmin 2.1 courier-imap,
runs pretty well since install
I need to transfer the mail server service to a new server running Ubuntu,
it came with Postfix 2.7.0
what the proper (easiest?) way to migrate current setup to the new server ?
--------
current# postconf -d | grep mail_version
mail_version = 2.4.5
current# postconf -m
btree
cidr
environ
hash
ldap
mysql
nis
pcre
proxy
regexp
static
unix
-------------
NEW# postconf -d | grep mail_version
mail_version = 2.7.0
NEW# postconf -m
btree
cidr
environ
hash
internal
mysql
nis
pcre
proxy
regexp
sdbm
static
tcp
unix
