Multi-account Functions, is a feature in WHM that saves you time when you want to perform a certain operation on many accounts. It lets you do that operation on all accounts at one go. The feature allows you to “Modify/Upgrade Multiple Accounts” and to “Change Multiple Sites’ IP Addresses“. If you only have reseller privileges you are likely to only have the ability to “modify/upgrade multiple accounts”.

1. Login to WHM to accomplish this task.

2. On the left sidebar menu, navigate to “Multi Account Functions” and select “Modify/Upgrade Multiple Accounts“.

3. You will see a long list of all your accounts.

You can search for accounts using certain parameters. Look on your right-hand side to see this functionality.

Select the package you want to upgrade/downgrade to. You can also change locale. Finally, click on the button “change”.
