# Upgrade to v2
If you already have a YunoHost version prior to RC (`beta2`, `beta3` or `beta4`), you should proceed to upgrade this way:
## 1. System
Connect to your server directly or via SSH, and run the following command:
```bash
sudo apt-get update && sudo apt-get dist-upgrade
```
## 2. Applications
Once upgraded, you can upgrade your applications too:
```bash
sudo yunohost app fetchlist
sudo yunohost app upgrade
```
**Note** : If you had installed unofficial applications (other than Roundcube, Jappix, Wordpress, TTRSS, Radicale, Agendav, Owncloud, PHPMyAdmin, Zerobin, Jirafeau or Transmission), you will have to upgrade them manually (or leave them like this).
