You can change plans at any time. The process to change plans is seamless and easy, and won't require you to export/import your wiki.
If you're on any plan except VPS: To start the process, go to "My Services" (https://panel.mywikis.net/clientarea.php?action=services). Click on the service you'd like to change the plan for. Press "Upgrade" (even if you are trying to downgrade your plan) and select the new plan and payment plan you'd like. If you are upgrading to MyWikis Pro, Corporate, or VPS from MyWikis Basics, please create a support ticket to let us know so we can add VisualEditor to your wiki.
If you're moving to a higher plan, you'll find a prorated invoice to pay for that covers the difference between your current plan and your new plan. The invoice needs to be paid in order for the plan change to be finalized. If you're moving to a lower plan, your next invoice will be delayed and any remaining credit left in your former subscription will count towards your new plan.
If you're currently on our VPS plan but want to downgrade: To start the process, open a ticket under the Billing and Provisioning department and let us know which plan you want, as well as whether you'll be paying monthly or annually. Your new billing will take effect when we respond to your ticket.
