I am trying to upgrade my current 220.127.116.11 to 18.104.22.168 and I am getting asked for licence files for each application I would like to enable. I have upgraded XMC many times and have never been asked for this. Is this new? When I follow the link to generate the licenses it asks for a voucher ID which I don't have.
4.1.1 License Renewal
Upgrading to Extreme Management Center version 8.2 requires you to renew your NMS license if generated prior to November 30, 2018.
Licenses generated prior to November 30, 2018 expire 90 days after upgrading to Extreme Management Center version 8.2.
Regarding the voucher - who generated the initial XMC license ? This person should know the voucher ID.
