This page lists procedures used to upgrade from 7.0 to 8.0.
Upgrade Path
Important
Before you upgrade or downgrade a cluster, ensure all cluster members are running. If you do not, the upgrade or downgrade will not complete until all members are started.
For any versions, major or minor, you can upgrade or downgrade to its adjacent neighbors. For example, you can downgrade from 8.3 to 8.2 or upgrade from 7.0 to 8.0.
For all versions, major or minor, you can downgrade to the immediately previous major version. For example, from 8.3 to 8.0.
For any minor version, you can upgrade to the immediately next version. For example, from 8.2 to 8.3.
If you need to downgrade from 8.3, downgrade to the latest patch release of 8.2.
