The difference is that you **select a lower-tier plan in the “Target plan”**. ### 1. Select a lower-tier plan as the target plan - Follow steps **1–4** from “Upgrade Instructions” above. - In “Upgrade / Downgrade to,” select a lower-tier plan than your current one (example: *Basic*). - Select the billing cycle, click “Continue,” review the details, and click “Submit” to confirm. ### 2. Important notes for downgrading - Whether downgrading takes effect **immediately** or **at the next renewal** depends on the service settings. Please always check the on-screen guidance and invoice details. - If a lower-tier plan is not available as an option, downgrading may not be possible due to the plan structure or contract terms. Please contact support. ## How to Add Failover Monitoring DNS failover monitoring (health checks on A records with automatic switchover on failure) can be added by upgrading to a Failover-ready plan. The steps are the same as the “Upgrade Procedure” on this page — simply choose a Failover plan as the target. **Target plans and pricing** - **Basic-Failover-One**: Basic + 1 failover monitor = **$5.36**/month - **Start-Failover-One**: Start + 1 failover monitor = **$9.92**/month Each adds 1 failover monitor for +$3.35/month over the base plan. The Business plan includes 1 monitor as standard. In Step 3 “Select the target plan” above, choose **○○-Failover-One** (e.g., `Start-Failover-One`), then continue and submit to switch to a Failover-ready plan. ![Select a Failover-ready plan as the upgrade target](https://bestnetllc.co.jp/wp-content/uploads/2026/06/dnsstep2.jpg) Select a Failover-One plan as the upgrade/downgrade target (e.g., Start-Failover-One, $9.92/month) **After upgrading** After upgrading, failover monitoring is configured per A record. For the configuration steps, see the “Failover / Monitoring” section of [How to Use the DNS Service (Operations Guide)](https://bestnetllc.co.jp/en/docs/dns-service-operations-guide-en/). ## Frequently Asked Questions ### The Upgrade / Downgrade link is not displayed - Verify that the service is in “Active” status. - Plan changes may be restricted based on your contract details or permissions. Please contact support. ### The amount shows $0 (or is different than expected) - The difference charge may be offset due to remaining contract days, credit balance, tax calculations, and other factors. - The final billing result is shown in “Total charge for today.” Please always review before submitting. ### The display is not updating after the plan change - Try refreshing your browser. - It may take some time for changes to appear. Verify that an invoice has been issued and that the plan name has changed in the DNS SERVICE list.
