I have ESXi current version 6.5 Patched ESXi650-202110001.
I would like to know the fix for ransomware ESXi650-202102001 is included in the version above or not?
If it is not included, could I able to install the pathed lower version?
Or it is better to patched in latest version?
Thanks a lot.
All ESXi patches are cumulative. I would suggest installing even ESXi 6.7 Update 3 latest patch.
All your licenses will still be valid. And do not forget to update your vCenter.
And even to check the compatibility of your hosts for vSphere7.
