1. Migration Completion Email
After successful transfer, an email with subject "VPN server migrated to new VPS — update client configurations" is sent to your WHMCS billing account email.
The email includes:
- old and new server IP addresses;
- server number in the panel;
- number of migrated clients;
- link to the management panel.
2. Verification in the Management Panel
- Log in to the panel via client area ("Server Management Panel").
- Open "Servers" — the server should have a new IP and Active status.
- Open "Clients" — all CLIENT IDs are in place, traffic statistics preserved.
3. Notifying End Clients
Important: do not send configuration files and QR codes directly. Provide clients with only their CLIENT ID and the address idconverter.com — the client will obtain current configs from the new server independently.
3.1. Client Message Template
Hello!\n\nOur VPN server has been migrated to a new platform. Your access key (CLIENT ID) has not changed:\nXXXXXXXXXXXXXXXX\n\nPlease obtain your configuration again at https://idconverter.com\nOld VPN files no longer work.\n\nWe apologize for the temporary inconvenience.
4. Post-Notification Monitoring
- verify that clients are connecting again;
- for individual issues, check that the client uses CLIENT ID, not an old file;
- for widespread problems — open a support ticket with the server number from the email.
