After creating a service plan, you may need to update resource limits or permissions. This guide covers modifying plans and understanding how changes affect existing subscriptions.

### Modifying a Service Plan

1. Log in to **Plesk**.
2. Go to **Service Plans** → **Hosting Plans**.
3. Click the plan name you want to modify.
4. Make changes to any settings.
5. Click **OK** or **Update & Sync**.

### How Plan Changes Affect Subscriptions

- **Synced subscriptions:** Automatically receive all plan changes.
- **Locked subscriptions:** Do NOT receive plan changes. These were customized individually.
- **Out of sync subscriptions:** Need manual syncing.

### Important Notes

- Reducing resources will not delete existing customer data — it only prevents new data from being added.
- Removing permissions takes effect immediately for synced subscriptions.

### Troubleshooting

**"Sync failed" error:**

- The plan includes resources not available to your reseller account. Contact your hosting provider.
