There should be other config files in /etc/dovecot/conf.d/ - if 12-replication.conf is not there you can just create it, but putting it in dovecot.conf will work too.
(it is easier to locate a specific configuration this way as to search a long dovecot.conf)

> server A. In other server (server B) Also I have the same configuration, except mail_replica line and it is pointing to the other server like, " mail_replica = remote:vmail at bal3200dev001.testorg.com <mailto:remote%3Avmail at bal3200dev001.testorg.com> ".

That's good.

The replication wiki says:

Make sure that user listing is configured for your userdb, this is required by replication to find the list of users that are periodically replicated:
doveadm user '*'

Did you try that?

I think doveadm user '*' will not work with static userdb because no users are actually configured.

You could try https://serverfault.com/questions/939418/how-do-i-configure-doveadm-a-with-passdb

passdb {
    args = scheme=sha512-crypt /etc/mail/passwd
    driver = passwd-file
}

userdb {
    default_fields = uid=vmail gid=vmail home=/var/vmail/%d/%n
    args = /etc/mail/passwd
    driver = passwd-file
}

I've never tested this as I have my users in a mysql database.

If it works you should see some output like the following from doveadm replicator:
