How to Apply a hotfix

Hotfix does not require going through the upgrade process, see the steps below.

1. Download hotfix
2. Extract the hotfix and overwrite VTiger files eg:

cd /tmp
wget -O hotfix.zip https://sourceforge.net/projects/vtigercrm/files/vtiger%20CRM%207.1.0/Core%20Product/Hotfixes/vtigercrm7.1.0-hotfix3.zip/download
sudo unzip hotfix.zip -d /var/www/html/vtiger/

If you are upgrading VTiger from one version to other you don’t need to apply a hotfix, as it has been already repackaged in the Source and Migration patch.
