Maildir sync between cpanel servers

Hi! Few days ago I needed to migrate a cpanel domain with 3 addon domain, and I wanted to move those addon domains to their own account. Problem was migrating all email accounts (500+) from addon domains with all emails. I had user-access (cpanel account) to the old server and root access (whm) to the new server, so I found a possible solution: synchronize maildirs between servers would allow an easy migration. (Yeah, I could simply copy all email files and dirs, but it took a long time and emails were still reaching the old server) For this task I used the excelent lftp tool and created a bash script for sync:

#!/bin/bash    
HOST="11.22.33.44"
USER="username"
PASS='s3cret'
FTPURL="ftp://$USER:$PASS@$HOST"

echo "Migrating etc"
LCD="/home/username/etc/example.com"
RCD="/etc/example.com"
/usr/bin/lftp -c "set ftp:list-options -a;
open $FTPURL;
lcd $LCD;
cd $RCD;
mirror --delete --verbose"

echo "Setting etc owners"
chown username:username /home/username/etc/example.com/* -R
chown username:mail /home/username/etc/example.com/passwd*
chown username:mail /home/username/etc/example.com/quota*

echo "Migrating mail"
LCD="/home/username/mail/example.com"
RCD="/mail/example.com"
/usr/bin/lftp -c "set ftp:list-options -a;
open $FTPURL;
lcd $LCD;
cd $RCD;
mirror --delete --verbose"

echo "Setting mail owners"
chown username:username /home/username/mail/example.com/* -R

# Horde symlinks
/usr/local/cpanel/scripts/linksubemailtomainacct username

Basically I copy /home/username/etc and /home/username/mail content from old server to new one. In each run, I used "mirror --delete" to delete local files (emails already deleted in source server), but after changing dns mx entries, I stopped using the "--delete" parameter I hope this can be useful to someone, someday... P.S be careful with propper directories location for mirroring and chown-ing!

Thanks, Michael! Hope you can tell me if you think the script is right or if I'm missing any step for mail migration and owner setting

One addition to consider would be to run the "/scripts/mailperm" script after the transfer. EX:
/scripts/mailperm $username
Thank you.
