I'm looking to patch (upgrade) from NSX 126.96.36.199 to 188.8.131.52 and for the sake of change management and everyone's peace of mind I need a rollback procedure for this. I know there are lots of checks in place to make sure it is successful, but I still need a tested rollback plan.
All of VMware documentation refers to upgrading from NSX 3.x to NSX 184.108.40.206 which is not what I'm doing.
Put simply, is the procedure to:
Redeploy a NSX 220.127.116.11 Manager Node.
Run the restore on that redeployed Manager Node (this should redeploy the NSX Manager Cluster with 2 additional NSX Manager Nodes)
Redeploy the NSX Edges through the redeployed NSX Manager UI.
Rollback the ESXi Hosts - this bit I'm not clear on and I haven't found a good document yet. I wouldn't use the Alternate Bootbank as it isn't a good option as VMware often update both as I found out when trying to rollback the latest ESXi 7U3i patch, i.e. it didn't roll it back and the server needed a rebuild.
