Overview

A user is planning to upgrade their Kayako Classic version to the latest one, but wondering whether they can upgrade directly to the latest release or if there is a recommended upgrade path as they are running an older release such as 4.78.1.

Solution

If the current version used by the Kayako Classic instance is older than 4.93, it is recommended to follow the incremental upgrade shown below.

One needs to follow this path since there were some significant changes on these versions such as the use of PHP 7 starting in version 4.93.0. The incremental upgrade helps ensure the instance is working as intended after each step.

To obtain the installation files for older versions, refer to the Where Can I Download a Copy of Older Kayako Classic Versions? article.
