Vault Enterprise Upgrade Process

Looking for some second opinions on upgrading a 3 node cluster.

Looking at the documentation, it looks pretty easy. I have a three node cluster w/ consul backend. We are upgrading from 1.5.7 to 1.7.X. Is there anything that i am missing?

  1. Shutdown standby node A

  2. replace binary w/ new version on node A

  3. Start node A

  4. do a vault login w/ root token to make sure node A is a follower

  5. Do the exact same steps for Node B above

  6. Finally shut down the Node C, which is the leader. Shutting it down will cause Node A or B to become leader. Replace binary on Node C and bring back up.

Is there anything else i should do?
