It is a best practice to create a backup prior to upgrading HCX Manager. See Backing Up and Restoring the System. This back up option may not be available in some Public Clouds where HCX is managed by the cloud service provider.

In addition to backing up HCX Manager, optionally use the vSphere snapshot feature to take a snapshot of the HCX Manager at the source and the destination sites. If necessary, you can use snapshots to roll back the HCX Manager version. See Roll Back an Upgrade Using Snapshots.
