Now that Ubuntu 16.04.1 has been released will Virtualmin support upgrading from 14.04 to 16.04 soon. I checked https://www.virtualmin.com/documentation/system/upgrades-and-migrations and I did not see a guide or any mention of it yet so I imagine that is not supported at this time.
Shoot, I’m apparently more behind than I realized. That will be up there soon
Ubuntu 16.04 is indeed supported, we’re just lacking the docs that show up to perform such an upgrade. But they’ll be there soon.
