Purpose

This article provides best practices information when upgrading your VMware vCloud Networking and Security 5.5.x to NSX for vSphere 6.2.x.
 
Note: This article was created based on upgrading from VMware vCloud Networking and Security (vCNS) 5.5.x to NSX for vSphere 6.2.0.

Resolution

Upgrade Order

To upgrade VMware vCloud Networking and Security 5.5.x (vCNS) to NSX 6.2.0, you must first upgrade the NSX Manager, and then upgrade the other components in the following order:

  1. NSX Manager
  2. Host Clusters and Virtual switches/wires
  3. vShield App (replaced by NSX Distributed Firewall)
  4. vShield Edge
  5. vShield Endpoint

Risk Assessment

Upgrades always have some inherent risk. Reducing this risk is paramount to a successful upgrade. To minimize risks, consider these:
  • In a backup environment, perform the upgrade steps to familiarize yourself with the process.
  • Verify that virtual machine workloads can migrate/vMotion to other ESXi hosts and that there are available resources for multiple host evacuations.
  • As an alternate, avoid the upgrade and perform a fresh install into a new environment and perform virtual machine migrations to the new environment.
    • Virtual machine migration: Some planning required.
    • vCenter Site Recovery Manager
    • VLAN - VXLAN bridge

Pre-Upgrade Checklist

Before you begin the upgrade, do the following:

  1. Verify that you have a current backup of the vShield Manager and vCenter Server.
  2. Take a snapshot of the NSX Manager (include its virtual memory) prior to the upgrade. For more information, see the NSX Manager Backup and Restore section in the NSX Operations Guide.
  3. Download and stage the upgrade bundle, validate with md5sum.
  4. Ensure vShield Data Security is uninstalled.
  5. On the vCNS Manager, run the show filesystems command to verify if sufficient disk space is available.

    Note
    : If you need to cleanup, run the purge log manager and purge log system commands and reboot.

  6. On the vCNS Manager Appliance, replace the e1000 network adapter with a VMXNET3 adapter. For more information, see vShield Manager version 5.5.x becomes non-responsive (2114813)
  7. Ensure that forward and reverse DNS, NTP as well as Lookup Service is working.
  8. If vSphere Update Manager (VUM) is in use in the environment, ensure that the bypassVumEnabled flag is set to true. This setting configures the EAM to install the VIBs directly to the ESXi hosts even when the VUM is installed and/or not available. 
  9. Quiesce all operations in the environment until all sections of the upgrade are complete.
  10. Take a snapshot of the vCNS Manager.
  11. Take a Tech Support Bundle. 
  12. Do not power down or delete vCNS App Appliance before instructed to do so.
  13. VMware recommends to do the upgrade work in a maintenance window as defined by your company.

Upgrade


For more information, see the vCloud Networking and Security 5.5.x to NSX 6.2 Upgrade section in the NSX Upgrade Guide.

Post-Upgrade

After the NSX Manager upgrade completes:

  1. Ensure that forward and reverse DNS, NTP as well as Lookup Service is working.
  2. Delete the snapshot of the NSX Manager that was taken Pre-Upgrade.
  3. Take current backup of the NSX Manager after upgrade.
  4. Validate that VIBs have been installed on the ESXi hosts by running the esxcli software vib list command and verify the following are loaded:
    • esx-vxlan
    • esx-vsip
    • esx-dvfilter-switch-security(prior to NSX for vSphere 6.2 versions)

  5. Force sync the message bus from the Host Preparation tab.
