1-grid is only able to downgrade/upgrade packages that we’ve created. If you created your own packages in WHM and assigned them to a customer, you would need to change the package yourself.
1. Log in to WHM.
2. Search for “list accounts”.
3. Expand the options on the left-hand side of the account you wish to change:
4. Click on “Change Plan”.
You’ll see a box with a list of other packages you created.
5. Choose the package you wish to assign to the domain.
