# For other full node operators

{% hint style="warning" %}
The documentation is designed for Liker Land and LikeCoin v2. For information on [3ook.com](https://3ook.com/) and LikeCoin v3, please visit [docs.3ook.com](https://docs.3ook.com) and [dao.like.co](https://dao.like.co/).
{% endhint %}

For non-validator nodes, or for validator nodes who cannot join the upgrade process, you may setup a [full node](/validator/likecoin-chain-node/setup-a-node.md) or replace your current full node after the upgrade is finished.

1. Clone the software if you haven't already have one:

   ```
   git clone https://github.com/likecoin/likecoin-chain
   ```
2. Switch to the `fotan-1` branch:

   ```
   git checkout fotan-1
   ```
3. Backup `docker-compose.yml` if you have one:

   ```
   cp docker-compose.yml docker-compose.yml.sheungwan
   ```
4. Setup `docker-compose.yml` and `.env` file:

   ```
   cp docker-compose.yml.template docker-compose.yml
   cp .env.template .env
   ```
5. Get the genesis URL, which will be generated (uploaded) during the upgrade process by validators.
6. Setup `.env` file according to the chain parameter:
   * `LIKECOIN_DOCKER_IMAGE`: `"likecoin/likecoin-chain:fotan-1"`
   * `LIKECOIN_CHAIN_ID`: `"likecoin-mainnet-2"`
   * `LIKECOIN_UID`: normally keep it as `"1000"` is fine, but if you are using root user under Linux (e.g. in some VPS) then you should change it to `"0"`.
   * `LIKECOIN_MONIKER`: the original moniker (in `.liked/config/config.toml`, search for `moniker`). If not sure, any name indicating your node is OK.
   * `LIKECOIN_GENESIS_URL`: `https://gist.githubusercontent.com/williamchong/de1bdf2b2a8f3bce50a4b5e46af26959/raw/4e21bff586771c849d22e1916bcb88c6463fbaa0/genesis.json`
   * `LIKECOIN_SEED_NODES`: `913bd0f4bea4ef512ffba39ab90eae84c1420862@34.82.131.35:26656,e44a2165ac573f84151671b092aa4936ac305e2a@nnkken.dev:26656`
7. Backup the original node if you have one:

   ```
   mv .liked .liked.bak
   ```
8. Initialize the node with new software:

   ```
   docker-compose run --rm init
   ```
9. Re-import the keys and address books from the old node if you have one:

   ```
   cp \
     .liked.bak/config/node_key.json \
     .liked.bak/config/priv_validator_key.json \
     .liked.bak/config/addrbook.json \
     .liked/config
   ```
10. Start up the node:

    ```
    docker-compose up -d
    ```
11. Wait for synchronization, which you may check by going to <http://localhost:26657/status> and see `result.sync_info.catching_up` . If it shows `false` then the node has caught up.
12. If you have keystore, you may migrate the keys by running the following command:

    ```
    docker-compose run liked-command keys migrate /host/.likecli
    ```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.v2.like.co/validator/previous-upgrades/fotan-upgrade-mainnet/for-other-full-node-operators.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
