cPanel Find Reseller domains and update Serial

Have you ever wanted to find all of cPanel resellers domains easily without hassle and update the serial in the DNS zone after a migration? Then your in luck.

Having had this issue and also needing to update the reseller’s domains SOA aka serial en masse I have written a script to find those domains parse out the subdomains and duplicates and then increment the serials for those domains.

This is the v3 script that simply finds all the domains for a reseller. It first finds all the user accounts owned by the reseller and then finds all the domains for each account under the reseller. It then removes subdomain prefixes and then removes duplicates so you have the base domain only.
