    Description

      Cluster Setup

      • Kind cluster locally run on Mac
      • 3 nodes with all services
      • 1 bucket
      • Initial cluster version : 7.2.5
      • Upgrade cluster version : 7.6.1

      Steps taken in the scenario

      • Created a cluster
      • Issued an upgrade from 7.2.5-7596 to 7.6.1-3200
      • Swap rebalance upgrade takes place.
      • Upgrade goes through fine
      • Post upgrade issued a deployment to downgrade back to 7.2.5
      • The deployment fails as expected but with an incorrect error message

      cannot upgrade from 7.6.1 to 7.2.5. Version must be less than 8.6.1.

      The lines cannot upgrade from 7.6.1 to 7.2.5. Version must be less than 8.6.1. is incorrect. Version 7.2.5 is less than 8.6.1 and that is not the reason why downgrade cannot proceed.
