# Update your server

Run as `sudo` / `root` user

:::hint{type="info"}
Reboot if you have a new kernel installed during the update that needs loaded.
:::

```bash
sudo -s &&
```

```bash
apt-get update -y && apt upgrade
```

# Stop old system service

Use  `status` to check if its running, `stop` to stop the service, and `disable` to prevent it from loading next reboot

```bash
systemctl status xand.service
systemctl disable xand.service
systemctl stop xand.service
```

# SSH Keys

If you want to make a new user `sol` to match the new guide, then make sure your ssh keys to login remotly are stored in your home dir for `sol` or `root` users (not only in `xand` home dir. Careful with the ssh keys...if you remove them you could lock yourself out of your server...

Check for keys in root

```bash
sudo cat ~/.ssh/authorized_keys
```

Check for keys in `xand`

```bash
su xand
```

```bash
cd ~
cat ~/.ssh/authorized_keys
```

Copy from xand and append to root keys file

```bash
sudo -i
```

```bash
sudo cat /home/xand/.ssh/authorized_keys >> /root/.ssh/authorized_keys
```

# Validator Keypairs

Make sure you have copied your validator keypairs if they are needed for the new server.

Otherwise they can be created new during install of the validator software. 

There is no reason to re-use the old one, only personal preferance.

# Remove xand user account

Once you have sucessfully logged into your server using either `root` or `sol` user, and copied/backed up any files you need, you may wish to remove everything from `xand` user and their files.

```bash
sudo -s
```

```bash
userdel -rf xand
```
