1. Preserved Without Changes
- CLIENT ID of each client (16 characters) — key for idconverter.com;
- server number in the management panel;
- link to your service and order in WHMCS billing;
- client and server traffic limits;
- names, contacts, access expiration dates, notes in client cards;
- accumulated traffic statistics (transferred to new VPN peers).
2. Changes — Important for Clients
- VPN server IP address (new VPS);
- WireGuard keys / configuration file contents;
- QR codes for connection.
Old configurations and QR codes stop working. Clients must obtain access again via CLIENT ID on idconverter.com.
3. Why CLIENT ID Does Not Change
CLIENT ID is a permanent client identifier in the VPN Vendor ecosystem. During migration, the system recreates VPN connections on the new server but links them to the same CLIENT IDs. Managers do not need to recreate clients.
