Citrix Xenserver 6.0 how to get Free licenses?

Question

Licenses for software and other works

Good afternoon. Maybe there are gurus of this miracle from Citrix here. The problem is this: there is an old xenserver 6.0. Since March of this year, support for free activation on these versions has been canceled.
Is it possible to upgrade from 6.0 to 6.5 and not renew the license? As far as I understood from the information I found, version 6.5 does not require licenses. Or do you still have to somehow update to the current version of Xena?

Answer 1

you can upgrade to XCP-ng for free
