I have installed ESXi 6.0 with an evaluation license.However I cannot power on the virtual machines since the licenses have expired.
Is there a way I can extend the license so that I can finish the testing for a POC.
There's no way to refresh the evaluation period without reinstalling.

Can I extend my vCenter 6.5 eval license (60 days)?

this is not entirely correct,
a trial can be exended, but you will need to speak to VMware sales who may give you an new time bombed license key to allow you to finish your testing. but this is at the descretion of the Sales team and SE.
I would advise you to reach out to your VMware reseller or local SE/TAM to ask.
