Upgrade Health Checker is an onsite tool suitable for users with large or complex environments, limited access to the internet, or existing automation and orchestration frameworks. Upgrade Advisor is suitable for users with a smaller environment who prefer a cloud-based, UI-centered experience.

You can learn more about about Upgrade Health Checker and Upgrade Advisor to determine which tool best fits your needs.

Upgrade Health Checker reports provide detailed information on potential blockers and warnings that need to be addressed before upgrading your ONTAP clusters, risks associated with your clusters, and information about new features and enhancements in the ONTAP version you're upgrading to.

You don't need an internet connection to run Upgrade Health Checker. It generates upgrade plans and reports onsite using your ONTAP cluster's current configuration data.

However, internet access is required for automatic tool updates. If your environment lacks internet connectivity, you can manually download the latest version of the tool from the Upgrade Health Checker tile on the NetApp Console Automation Hub.

Upgrade Health Checker supports upgrades to ONTAP 9.11.1 and later.
