# LUMIA migration Sepolia to Beam

**Who this is for:** LUMIA holders whose tokens live on a Sepolia-based deployment and who need to move them to Lumia's Beam testnet.

### Network status

{% hint style="warning" %}
Lumia's current, live testnet is **Beam**. See [Networks & endpoints](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/reference/networks-and-endpoints) for its chain ID and endpoints.

A separate, unrelated network sometimes called "Lumia Testnet" is retired. Its RPC and its explorer are both dead, and it is **not** Beam. If something you read elsewhere gives a "Lumia Testnet" chain ID that does not match the Beam chain ID at [Networks & endpoints](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/reference/networks-and-endpoints), treat it as the retired network (see [Retired testnet (1952959480)](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/reference/retired-testnet-1952959480)), not as another name for Beam.
{% endhint %}

### Before you migrate anything

{% hint style="warning" %}
Do not use a migration tool, a contract, or a link you have not verified through an official Lumia channel. If you are unsure, ask support first, not after sending a transaction:

* Telegram: [@lumia\_helpdesk\_bot](https://t.me/lumia_helpdesk_bot)
* Technical support: `service@lumia.org`
