It is not possible to downgrade/upgrade from the dashboard.
Contact us for upgrading/downgrading
If you need to change your plan, get in touch with us, we'll help you with this.
You will have to subscribe to the desired plan and we'll cancel your current plan. Depending on which plan you choose, we might need to change your server (i.e. moving from Multiple sites to Custom).
If you have doubts about whether you should upgrade/downgrade, you can always ask us.
