How to upgrade system

When there's a new version available, you can find the information in System Modules

Download the upgrade package, for core upgrade, usually it is very big, not easy to upload via GUI, you can download to your local computer and then upload to server via FTP or SFTP, or you can ssh to the server and download to astercc directly
- For example, the link to download is http://download1.astercc.org/packages/core/core-2.2-rc2-patch-x86_64.tar.gz

cd /var/www/html/asterCC/data/_cache/
wget http://download1.astercc.org/packages/core/core-2.2-rc2-patch-x86_64.tar.gz

When you upload (or download) the package, refresh the page, you can find the “Upgrade” button
Click the button to perform the upgrade

During the upgrade, please make sure you don't have ongoing calls

You can also upgrade in ssh

tar zxf http://download1.astercc.org/packages/core/core-2.2-rc2-patch-x86_64.tar.gz
cd core-2.2-rc2-patch-x86_64
php install.php
