How to Upgrade Koha to Stable Version

A new version of Koha is regularly released every six months with new features and enhancements. Each koha release has a version number that consists of the year and month of the release. Here are the easy steps to upgrade the koha to a stable release.

Before upgrading koha to a new version, I would recommend taking a backup of your koha database. 

Apply the following commands in the Terminal

Upgrade the Koha

sudo apt-get update

sudo apt-get upgrade

install the repository key for the latest stable version

echo deb http://debian.koha-community.org/koha stable main | sudo tee /etc/apt/sources.list.d/koha.list

sudo apt-get update

Install the latest koha version

sudo apt-get install koha-common

Clean the packages after upgradation

sudo apt-get clean

Upgrade Database Schema

('library' is the name of the koha instance)

Rebuild the Zebra Index
