You will be presented with the information about support:

The installer will find an existing VMFS partition with an existing installation for upgrade. Select it.


You will be asked wherever to upgrade ESXi or overwrite the existing installation and wherverer to preserver the existing VMFS partiotion. Select ‘Upgrade’ option:
