VMware Blockchain provides an upgrade workflow that introduces some operational changes before, during, and after the upgrade process, which you must consider before you upgrade.

You can implement an in-place upgrade workflow to upgrade the Replica and Client nodes in a blockchain.

The in-place upgrade updates the Replica nodes within the blockchain. These nodes are backed up and upgraded consecutively. During the upgrade, the nodes are powered off.
