- Deciding whether to use the Upgrade and Revert/Downgrade Guide
This guide describes how to manually upgrade, downgrade, or revert an ONTAP cluster or a MetroCluster configuration using the manual nondisruptive or disruptive upgrade process. It also describes how to perform an automated upgrade using the command line interface (CLI). - Selecting your upgrade, downgrade, or revert procedure
When you update the ONTAP software, you must use a different procedure depending on whether you are upgrading, downgrading, or reverting the software. - Updating software on ONTAP clusters
Upgrading or downgrading a cluster to the current ONTAP release requires planning, preparation, the upgrade or downgrade itself, and several post-upgrade or downgrade procedures. - Reverting clusters to an earlier ONTAP release
In some cases, to transition a cluster to an earlier ONTAP release, you must perform a reversion. Reverting is always disruptive, and it requires planning, preparation, the reversion itself, and several post-reversion procedures. - Optimal service availability during upgrades
Service availability during ONTAP upgrades can be optimized through planning and configuration. In many cases, upgrades can be completely nondisruptive from a client perspective. - Contacting Support
You can contact Support to obtain help for your issue. - Notices
