How to reset VMWare ESXi evaluation license

Make sure that the SSH service is running on your ESXi host.

Open an SSH session to your ESXi host.

Run the following commands;

rm -r /etc/vmware/license.cfg
cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg
/etc/init.d/vpxa restart

The license is again valid for 60 days after the vpxa service is restarted.
