# Docker - Upgrading Your Node

### Pundi AIFX Network Upgrades

> For more information on past upgrades and instructions, refer to [**Upgrade Versions**](../versions).
>
> You may refer to this [**Countdown Timer**](https://pundiscan.io/pundiaifx/block/countdown/19908000) which will countdown the time till the upgrade height.

### Upgrade steps

1. Ensure you have stopped the docker container to stop node❗

```
docker stop fxcore
docker rm fxcore
```

\*fxcore is a container name, change the container name according to your setup

2\. Pull latest docker images

```
docker pull ghcr.io/PundiAI/fx-core:8.6.1
```

3\. Update config files

```shell
docker run --rm -v $HOME/.fxcore:/root/.fxcore ghcr.io/PundiAI/fx-core:8.6.1 config update
```

4\. Restart docker container to start the node:

```shell
docker run --name fxcore -d --restart=always -p 0.0.0.0:26656:26656 -p 127.0.0.1:26657:26657 -p 127.0.0.1:1317:1317 -p 127.0.0.1:26660:26660 -p 127.0.0.1:8545:8545 -p 127.0.0.1:8546:8546 -v $HOME/.fxcore:/root/.fxcore ghcr.io/PundiAI/fx-core:8.6.1 start
```

To check if fxcore is synced:

```bash
curl localhost:26657/status
```

Return:

```bash

To ensure that the blocks are synced up with your node, under "sync\_info", "catching\_up value" should be false `"catching_up value": false`. This may take a few hours and your node has to be fully synced up before proceeding to the next step. You may cross reference the latest block you are synced to "sync\_info": "latest\_block\_height" and the latest block height of our Testnet blockchain on our [Testnet blockchain explorer](https://testnet-explorer.functionx.io/fxcore/blocks) or our [Mainnet](https://explorer.functionx.io/fxcore/proposals).

> Make sure that every node has a unique `priv_validator.json`. Do not copy the `priv_validator.json` from an old node to multiple new nodes. Running two nodes with the same `priv_validator.json` will cause you to double sign.
