- Plesk Onyx for Linux
For example, reseller John Doe already has Reseller Plan - 10 Domains and it is required to sell him more resources. For example, by upgrading his current plan to Reseller Plan - 30 Domains.
In Plesk + WHMCS integration, in order to add more resources for reseller, it is needed to upgrade his plan:
Create the new Reseller Plan "Reseller Plan - 30 Domains" Plesk > Service Plans > Reseller Plans > Add Plan. Edit it as needed;
- Create the new Reseller Plan "Reseller Plan - 30 Domains" at WHMCS > Setup > Products/Services > Products/Services;
At WHMCS > Product > Setup > Products/Services > Products/Services > edit Reseller Plan - 10 Domains, and make sure and "Reseller Plan - 30 Domains" products are specified at Upgrades Tab.
Login as John Doe in WHMCS > go to Customers > Login as customer > Services > My Services > View Details > and click on Upgrade/Downgrade;
Note: During this setup, one might face the bug EXTWHMCS-34. If that happens, proceed with the workaround from this article: Unable to change package for reseller in WHMCS: Request is invalid. Error in line 5: Element 'id': '' is not a valid value of the atomic type 'id_type'
