After doing a WHM multi-account copy, you may want to refresh the users home directories (including email and web files). This one liner uses rsync over SSH to do a quick sync of only changed files, emails, and website files. Run these commands on the NEW server.
First you need to create a list of domains in a text file ‘domains.txt’. Replace 188.8.131.52 with the remote hostname or IP.
while read i ; do rsync -aHxv firstname.lastname@example.org:/home/$(/scripts/whoowns $i)/ /home/$(/scripts/whoowns $i) ; done < domains.txt
Alternatively, you can use a list of users instead of domain names (use this method if there are multiple domains per user):
while read i ; do rsync -aHxv email@example.com:/home/$i/ /home/$i ; done < users.txt
