Hi, I have read several questions about this but i want to have a more clear answer for my case.
I have a free license not installed by me of a 4.1 esxi. I want to install an essential license.
1) Do i only have to insert a license key?
2) do i have to install something or insertint the license key is enough?
3) do i need to be the owner of the free license key or the new license will just substitute the old one?
4) will all features be unlocked?
5) is it true that i need to reinstall esx in order to have service console?
thanks in advance
