# Upgrade your applications
|
|
|
|
Once you installed applications, you may need to upgrade them, sooner or later.
|
|
|
|
**Caution:** please be advised to backup your databases (using phpMyAdmin application for example) and files before any upgrade.
|
|
|
|
### Upgrade using the admin panel
|
|
Go to Tools > Update system
|
|
|
|
Once the applications packages list is retrieved, you will be able to update official applications that have a pending upgrade.
|
|
|
|
### Upgrade using command line
|
|
First, connect to your server through SSH and type in the following command (WordPress update):
|
|
```bash
|
|
yunohost app upgrade wordpress
|
|
```
|
|
**Note:** in case you have multiple instances of the same type (ex: 2 wordpress) installed, you will need to specify the instance name (ex: wordpress or wordpress__2).
|
|
|
|
#### Upgrade an unofficial application
|
|
Specify the Git repository containing the upgrade.
|
|
|
|
For intance, to upgrade LimeSurvey:
|
|
```bash
|
|
yunohost app upgrade limesurvey -u https://github.com/zamentur/limesurvey_ynh
|
|
```
|
|
|
|
**Note:** be cautious when installing unofficial applications and upgrades. Be sure that theses updates are stables and are not a step in the development process. There may be a good reason if an application is not listed in the official repository.
|
|
|
|
**Caution:** be sure to check the content of any update; installing or upgrading an unofficial application allows it to run scripts with the highest privileges.
|
|
|
|
#### Command line options
|
|
|
|
When upgrading apps from the command line, you can specify specific options to change the behaviour of the upgrade script.
|
|
To set those options, set the corresponding variable before the upgrade command: `sudo OPTION_TO_SET=1 yunohost app upgrade wordpress`
|
|
|
|
Available options are:
|
|
- `NO_BACKUP_UPGRADE`: Do not perform the backup before the upgrade. Which means the upgrade will be operated without a security backup.
|
|
- `YNH_FORCE_UPGRADE`: Force the upgrade of the app and the package, even if the app is already up to date.
