Upgrade Hyper-V Cluster 2012 R2 to 2016 before or after adding more nodes?


  • Hi all,

    I'm currently running 4 x 2012 R2 nodes at one site.

    Now I'm planning to add 6 more nodes, stretching the cluster out to a secondary DR site (5 and 5 nodes at each site), and upgrading all of the nodes and cluster to 2016.

    What are the pro's and con's of upgrading all of the nodes BEFORE shipping half of them to the DR site?

    Thanks in advance!

  • My personal route would be to get everything working locally before splitting it apart.  Tends to be a little easier to troubleshoot.  And, it ensure you are not troubleshooting any long distance networking issues while making sure the rest of the environment is working.  I would upgrade everything in a single site to ensure everything is working fine before splitting it between sites.  Just my preference.
