Release Timeline and Rollout

Updates to Primo are delivered every three months. These updates include security issues, new features, feedback on design issues, escalations related to specific functionality, and other issues.

Ex Libris upgrades cloud environments as soon as a new release of Primo is available, following an extensive QA process. We make certain that our hosted customers are the first to benefit from the latest enhancements and bug fixes.

By establishing the structured process, upgrades are more frequent and the gap between the current version and the new version is small.

The rollout of each new version is gradual and begins with institutions that are using Primo in the Ex Libris cloud environment. Prior to the upgrades, a message notifying cloud customers of the date of the upgrade will be sent out by the cloud team.

The upgrade process will consist of two steps: first, the new release is installed on the sandbox environment where applicable. We trust that you will try out the new version during this time. Two weeks later, the new release is installed on the production environment.  Consortia environments will have a four weeks test period.

Five days in advance, Dedicated customers will receive a message containing the exact install dates for both sandbox and production, which will occur within five weeks of the MT sandbox installation date.

 Key Benefits

Streamlining the release process will allow Institutions to –
