Upgrading Seldon Enterprise Platform (Seldon Deploy previously)

Important: When upgrading Seldon Enterprise Platform, please, always use matching version of the installation resources that is downloaded. This is especially important for the Seldon Enterprise Platform Helm charts as these may contain updates.

Important:

  • Seldon always recommend to first validate upgrade path in development cluster before rolling out changes to production.

  • Model artifacts trained to work with pre-packaged model servers may require retraining when upgrading. This is due to changes in their dependencies or in their Python versions. Advanced monitoring components -- model explainers, drift detectors, outlier detectors, etc. -- are the most likely to be affected.

  • Seldon recommends testing these artifacts in a development environment to determine whether or not they require retraining. Alternatively, you can modify the Helm values to specify previous versions of the relevant model servers.

Important: Seldon only support upgrading to the next released version of Seldon Enterprise Platform (Seldon Deploy previously). This means that if you for example are upgrading from Seldon Enterprise Platform 1.3 to Seldon Enterprise Platform 1.5 you need to first upgrade to version 1.4 and only then to version 1.5

Note: Keep your configuration files, e.g. Helm values of Seldon components, under VCS. This will allow you to easily rollback the installation if required.
