Is it possible to upgrade directly from 15.04 to 16.04?

I am running Ubuntu 15.04 on my laptop. Is it possible to upgrade directly to 16.04?

• No you can not upgrade from 15.04 directly to 16.04.


• You have to update from 15.04 over 15.10 to 16.04.

Just as additional information:

• Upgrading from LTS to LTS works (example: 14.04 to 16.04 would be possible)
