Hello, we have server with Ubuntu 11.04 which is running Wowza Media Server version 3.0.5. We now need to upgrade the karnel to Ubuntu 14.04 or 16.x latest My question is, if there will be any issue with older version of Wowza which is 3.0.5 with License. Or, if we need to upgrade the Wowza, will be okay our previews license number?

Hello,

I see this issue was discussed in a ticket with sales.

If running the latest Ubuntu 16.x you would need to upgrade to Wowza 4.x.x.
