Before we upgrade

It is very important to validate all necessary components before NSX is upgraded.i have already shared upgrade impact in my previous post , also below checklist will help you to prepare your environment to upgrade:

  • Download NSX upgrade bundle and check MD5.
  • if you are upgrading from 6.2.2 to 6.2.3/6.2.4. , there is known bug which affects EDGE upgrade when incorrect ciphers are configured. VMware KB NSX Edge is unmanageable after upgrading to NSX 6.2.3 explain steps needed to check it and/or change it before the upgrade.
  • Understand the  Update sequence for vSphere 6.0 and its compatible VMware products.
  • Backup of components:
    • Take a backup of NSX Manager (if you are not doing it regularly) before the upgrade.
    • Before upgrading download technical support logs.
    • Export of vSphere Distributed Switches configuration.
    • Create a backup of vCenter Server database.
    • Take a snapshot of vCenter Server and vCenter Server database.
    • Take a snapshot of NSX Manager (without quiescing VMware Tools, because it is not supported and it might crash your NSX Manager).
