I have install iredmail on CentOS 8 with the same settings as my old iredmail server on CentOS 7.
I am planning to Migrate my Emails and Accounts to the new server.
Here the steps that I am planning to take.

Based from this - https://docs.iredmail.org/migrate.to.ne … erver.html

1. rsync my vmail directory to vmail directory on the server.
rsync -avzhe ssh /var/vmail/vmail1/example.com/ root@192.168.200.8:/var/vmail/vmail1/example.com/

2. Export Databases from Old Server to new Server.
# vmail
# roundcube
# Amavisd
# iredapd
# iredadmin

3. Update iredmail up to version 1.3.2
    Update iredadmin up to version 1.2

4. Update DNS Records (DKIM)

My worries are:
1. I have test upgrade iredadmin 1.1 and 1.2 it is not working (probably because i am still in apache)

Is there anything i need to prepare?
