Coming from another panel

The pages are in the same places. The words map like this:

Xray panels	Marzban	W-UI
Inbound	Inbound (Xray config)	Interface — one WireGuard / AmneziaWG / OpenVPN tunnel
Client (email)	User	Client — a customer, with one account per device
Client's id / password	User's proxies	the device's key (WireGuard) or username + password (OpenVPN)
Total GB, Expiry, IP limit	Data limit, Expire, —	Total traffic, Expiry, Device limit
Subscription URL	Subscription URL	Subscription link — same idea, with a customer page
Hosts	Host settings	Hosts and host groups
Outbounds / Routing / Balancers	Core settings	Outbounds / Routing / Balancers — same tabs
Xray settings	Core settings	Engine (basics, balancers, DNS, advanced)
numbered menu	marzban CLI	w-ui menu, the same numbering
Restart Xray	Restart core	Restart tunnels
Nodes (multi-node)	Marzban-node	Nodes — other W-UI panels watched over the API
Telegram bot	Telegram bot	Telegram bot

What has no equivalent

• REALITY, VLESS, Trojan, Shadowsocks — not here; this panel runs WireGuard and OpenVPN. Where those protocols are needed for DPI, AmneziaWG is the obfuscated option.
• Multiple admins — one administrator per panel.

What is new to you

• Enforcement in the kernel — quota overshoot is one packet, not a polling interval.
• Fail-closed default outbound — when the hop everything leaves through is down, traffic is dropped rather than leaked from the server's own address.
• A certificate for the IP — HTTPS without a domain, from the first minute.

Moving customers

There is no importer for another panel's database: the credentials are different kinds of thing (Xray UUIDs vs WireGuard keys). Create the customers here — bulk creation takes a prefix and a count — and hand out new configs.
