How to Upgrade
Perform non planned upgrades only if you are having serious issues with your current version of the product or you are told to do so by the Support Team. In all other cases continue using your current version and plan routine upgrade at a later date. Beware upgrade process is error prone and fragile due to the complexity of the application and a lot of integration points with Squid and operating system so it does not always go smoothly. Backup before upgrading!
Before any upgrade please read the release notes for the new version at article Version History. There might be some major breaking changes in the new version that will require careful planning during pre and post update phase.
Then, to upgrade your current installation of Web Safety ICAP Server to version 7.3 follow these steps.
