There are two ways to upgrade an NDB Server: one-click upgrade and offline upgrade. One-click
upgrade is the recommended method, as it automatically downloads and installs the latest NDB
software version from the Nutanix portal. Offline upgrade is an alternative method, which requires
you to manually download the NDB software bundle and upload it to the NDB Server VM. Both
methods require you to have a valid Nutanix account and an internet connection. Reference::
